Hi everyone, I'm awaiting the first hatching of shrimplets from my two pregnant Red Cherries; it's almost week 3 for one of them. I'm fairly new to shrimping, so this will be my first experience with this. A quick synopsis is I have one male and two females and the surprising thing is that all three are so different looking! Naturally the male is different, but the females too. One is much larger than the other, and has about 75% striated red coloring. The other female is smaller, but has almost 99% red (sometimes crimson) coverage, and is much shyer.

The first 3 pics, I took a couple weeks after getting them, so perhaps about 1.5 - 2 months old?

This is the larger female early in her pregnancy; she had a lot of eggs and I even noticed some excess on a plant. She's colored up more since this pic.

A comment I'd like to make is that I've seen a few pics "depicting" shrimps mating. The ones I've seen show the male alighted on the back of the female. However, that is not what I observed, so could Red Cherries be different?

What I observed was, while passing by the tank, I noticed a female lying on her side in the open and I thought, "Oh no, she's dying." For after all, shrimp seem to just keel over when dying. Upon closer inspection, I thought I saw a molted exoskeleton on her underside. But it was the male lying on his side too, and they were embraced, face to face. They stayed like that for about 7 more seconds (I have no idea how long the whole thing took, for I happened upon them in progress), then they sprang apart. Then within the next hour or two, I watched the process of eggs descending down into the pleopod area of the newly mated female.

Here's the female with the almost full red coverage.

She's actually carrying eggs in this particular pic but has much less than the larger female. I usually have a tough time seeing her eggs.

I've really come to enjoy the male Red Cherry - almost more than the females! I rather like that he's distinct from the females, so I'll just let the females have the glory with the red. The males are so cool how they "hover swim" like miniature flying horses. Even their hanging legs make them look like they're galloping. :~D I don't usually see the females swimming around like that; perhaps because the "swimming" is more related to the male's need to search for females.

GunmetalBlue,

Good piece of information. Get our camera ready and hope to see the XXX actions capture on film. :)

Did you observation the eggs get bigger over time or the size stay contant once they get out of the body?

Hi GB,

Nice red cherry shrimp you have. What do you feed them and how you make them so red?

Thanks Jojoecute, I appreciate your info - so it sounds like variety is okay! :D

Fruitpie, I will catch you up on the XXX action in a second ;) . About the eggs, it seems like they might have gotten a little larger with time, but I never noticed any eyes. They were hard to see though, because both moms hid a lot, making the egg progress difficult to observe.

Thanks Wifi, I think the red will mostly be genetic because all they seem to eat is algae. Or perhaps eating algae helps them? I've got lots of algae, so they ignore anything fed to them. I feed the Bamboo shrimp in there about twice a week, mostly a crushed mixture of flake, FD bloodworm, FD brine shrimp and Cyclop-eeze, all swirled into the water. It's possible the Cherries pick some up, but when I've put algae wafer in the tank, they ignore it.

Hi Class 66, thanks, that's a really nice thing to say. :)

Update on hatching: Last night before going to bed, I noticed the eggs were gone from the more red Cherry. It was she that was due, so I guess the shrimps hatched - but as hard as I stare into the tank, I just can't see any shrimplet :( . She didn't have as many eggs as the other shrimp, so trying to find a few shrimplets in a 20 gallon is proving to be difficult. The other female's eggs should hatch in 3 - 4 days.

Today, I saw two molted exoskeletons. They could only be the more red female's and the male's, because the other female is still pregnant and I understand they don't molt during pregnancy. So tonight, I caught them in the act! The male, while advancing on the female kept fluttering his swimmerettes. Perhaps a message of some sort? Please forgive the poor quality of the first pic, they were just too far away and the timing, too short. It's not like I can ask them to please come closer to the camera or ask them to pose again lol . But if you squint, I hope you can see them lying on the gravel together.

They tried again later, :love: this lasted longer and think it was a take; an hour later, her eggs had dropped down into the pleopod area - so she starts this process all over again! Poor little lady. :smug2:

Thanks for posting, those shots are really great and to finally see them in action ... wow! Hehehehe ... I have seen them before but it is different whe it is captured on film, of course.

Your cherry is very red, mine is on the deep darker red side ... don't have a camera otherwise I would try my hands at photography lol

Thanks Walter and Marge :smile:.

Marge, it sure would be nice to see pics your shrimps one of these days!

Well I am happy to have finally spotted a couple of shrimplets yesterday and am officially a grandma :happy2: . I think the Cherries will feel more comfortable after I get a nice group of them going. There's plenty of room in the 20 gallon, it'll be great to be able to see some at any given time.

2 day old RC Shrimplet already hard at work doing what all babies do: Eat and poop! :D

Thanks again, Marge, I would suppose you are a great-great-great Grandmummy by now. lol :)

Hi 900801, Red Cherry shrimplets are self-sustaining at birth, they are like miniature versions of the adults and will begin foraging for food such as the plentiful amount of algae I already have in the tank. So you don't have to do anything special. Just make sure to have a sponge cover for the inlet of your filter so they don't get sucked up.

Hi GunmetalBlue,

I am also wondering why moulting happens during pregnancy. There should be losses when it happen. See the attached pic, I lost an egg, it is about to hatch, the eyes were showing up.

GunmetalBlue
13th Jul 2005, 03:45 PM
Fruitpie, I think the reason why females don't or shouldn't molt during pregnancy is because of the nature of a molt. Basically, the carapace on top of the head splits from the tail section and the whole exoskeleton comes off, including the pleopod section. If eggs are still on it, it would have to separate away from the mother and therefore, usually not survive.

But nature has worked it out because mating takes place just after a molt. That means a mother typically won't molt within the time frame of carrying the eggs, which is say, 3 - 4 weeks. Then after the eggs have hatched, she is free to molt, mate and carry eggs again.

Did you lose only the egg or the mom also? If you lost just the egg, it might mean either it was too slow hatch, and the mother went on with a molt or there was some type of stress and the mother molted a little early, not giving all the eggs time to hatch. :(

Nice pictures u got .
Would like to ask which camera model you are using cos am getting a reasonable one soon.Dun wan to get one then regret. :embarasse

Secondly wat is the temperature of ur tank?any chiller used?
Thanks in advance.

GunmetalBlue
23rd Jul 2005, 04:18 PM
Hi Star88, I have an old Nikon 5700 digital camera. Most shrimp pics are taken using the macro feature, so check to see if whichever camera you want to get takes good close-ups using that feature. And when you do get your camera - take a bunch of pictures until you're finally satisfied you've got some okay ones. Since it's digital, it's all free to download into your PC, eh? :nice: :computer:

No chiller. Normally the temp stays between 77 - 79 degrees, but we're having a heat wave right now. So I've had the aquarium lid open and have been using a small plastic desk fan to try to keep the water 80 degress and under if I can. Works well, but I only use the fan if I'm home to monitor the temperature because I have to manually turn the fan on and off, depending on temp. I replace evaporated water with distilled water.

Hi GunmetalBlue,

I lost egg or eggs, perhaps more eggs will be detached while moulting and dropped to gravel. I didn't find any dead shrimps that day.

It is sad to lose that baby, its 2 little eyes staring at the camera. :(

Wow, those are spectacular photos!

What an interesting difference between your two females. Do you know if they are the same age, or came from the same "batch", or even the same colony?

*polite cough*.....gosh, I sure didn't expect to see the "action" shot, LOL! Talk about up close and personal. That's very interesting though, and I must admit I HAVE been wondering about that. I've never yet caught mine in the act.

Thanks for a great thread, you explain their actions and behaviours very lyrically!

And Fruitpie, that's such a technically lovely picture, but with such a sad content - the little abandoned egg. Poor thing.

GunMetalBlue, your shrimp sure do look healthy and happy! Do you supplement with iodine? Has the other female had her eggs yet?

-Jane

14th Dec 2005, 03:57 PM
Hi Jane thanks! And welcome to the forum. :) I got the shrimp from the same store at the same time - so they were in the same batch and could very well have been related, but really don't know. Yes, they were about the same age. Unfortunately I lost the less red Cherry some time back when I had a temporary water problem.

I don't supplement with anything extra. I do grow algae on plastic plants and decorations in a separate tank then place into their tanks; it's fun to watch them devour it. Other than that, their current regimen is flake or wafers every other day.

I must say, RCS multiply fast! It's been about 4 or 5 months since originally posting this thread; hope you guys won't mind my updating their current situation.

After the 5th batch of shrimplets (resulting in about 125 shrimplets total), I had to do something since I was starting to run out of room (What do you guys do when the breeding goes nuts?). I deliberated on different options and finally decided to slow them down by separating the offspring according to sex. So the only male and female together in a breeding tank is the pair that uh, *cough, cough* was seen in action. :p

Got a pic of this RCS shrimplets minutes after it was born. The head still looks like an egg! Except now, with an unfurled tail:

To explain what I have done in separating the shrimp by sex, I've turned my 20 gal into what I jokingly call my "All Female RC Shrimp Utopia." :D I'm embarrassed to show my tanks since they are all "no maintenance" tanks and not very exciting to look at so please bear with me - but I really like looking in there and seeing the little red ladies. Bet a male RCS would like to accidentally get put in there, eh? ;)

Here's one of the young females with unfertilized eggs; I wasn't at first entirely sure if RCS will carry eggs without fertilization (I know certain Macrobrachiums do) - now I know for sure they will, even if for a very short time. There was one that actually carried for 4 days and had me worried! I thought maybe a male was hiding in there with a disguise on (yellow paint, anyone?).

When the water clarity is so good it make the tank look even better even when it's a simple setup.

Wow, GunMetalBlue, I think your tank is Lovely! I like the simplicity. It brings the focus to the shrimp.

When you said its a "no maintenance", do you just mean no CO2? Are those vals in the back? Are they planted in the substrate? Your water clarity is amazing.

Great looking tank. And again, your photography is top notch! I love the pict of the just-hatched baby! Thanks for sharing these with us.

Whaa, you guys are just too nice concerning my humble tank, thank you. Marge, the ladies thank you too! :gorgeous: :D


When the water clarity is so good it make the tank look even better even when it's a simple setup.
Was I supposed to put water in there? :shocked:

Jane, yes, this is a serious "no maintenance" tank, no dosing, no nothing.

>I do 15% water change once a week.
>Scrub glass as needed.
>When filter flow runs a little slower, I rinse out sponge on the intake with used aquarium water (about every 3 months or so); same with part of the filter media sponge on an alternative basis - a very occasional squeeze.

The current load in the tank is light - 2 Bamboos and so far, 25 young females; more will be added from my other tanks when I'm sure of their sex. I do have to prune dying leaves on the plants since they don't do so good, oh well *sigh. :tired:

Yes, those are vals in the back and most of my plants are in those little pot containers (I know, very silly...) - which means I can move them around whenever I want - very convenient when I want to scrub the glass towards the back or sides or have to remove something. That's how seriously functional this tank is! :p

Hi,

This was the most red cherry i ever had...I can note that there's a lot of veriety in color, some of my females are more red spoted, some have wite spots in legs, and others are really red like this one.In this case the strip in the back is missing. I have others females that have this strip.

It may look really big but this one is actually small. You can see a offspring in the front, not focused.

I didnīt use photoshop or any other program, this was her natural color.

I never fed my shrimps. They ate algae and fish wasted food.This was my first female and is the ancestral of every red cherrys that i have in this moment. I will start a program of selectin breeding to select the red ones like her:

Puku and RI, very kind comments, thanks! :blush:

Nuno, that is a lovely female and the ones like her should be the perfect choice for your breeding efforts! :) I've also noted the varying color coverage in different females, the original that I started with had some white/clear spots, most of it on her legs. Out of the batches I have now, there are about 2 or 3 that has complete color coverage, no spots of white. So when I do want more Cherries, they will definitely be my breeders.

Cambarus, so nice of you making your first post here, thanks for sharing :) . Another beautiful lady; I see that she has the stripe on her back. My original female had the stripe too, and at times it showed very brightly. BTW, the CRS on your avatar ... yowza :shocked: .
