Shrimp ID Please

[gnatster]

Picked up some of these at my local fish store (lfs). The tank was unlabeled and no one of importance was available to help. Any idea what they are?

Thanks

Hi gnaster,
I can't help you because the images don't work. I copied the url of the pics and pasted them into a new browser window but it does not work. It's a problem with the APC gallery. Maybe you can upload them here into the gallery too and we can help you.

best regards

Robert

As of this writing the pictures do not work as APC is down. Images will come back as soon as APC is back online. Sorry for any inconvience.

Update, site back up, pictures now showing again.

Hi Gnatster, although the color is off, the first one looks like a female Red Cherry. In real life, is it clearish, with red markings?

Can't really tell what the shrimp in the second pics are. :huh:

Thats no Red Cherry, I have tanks full of Cherries and have never ever seen one close to that. The colors in the photo are close to being spot on. It really is a yellowish hue like that. Whats interesting is a freidn of mine just coordinated a group order for Amano shimp and they were sent 500 like I have above by mistake. He's sending me more to go with the ones I picked up locally and we'll see what happens.

I've never seen the wild form, but could it be some type of Neocaridina though? I'm going by the fact that the picture seems to depict it has a saddle. I'm also looking at the face.

Hmm true or false you decide this is what i know,

The shrimps above are called "black shell"(I have no idea who named them) shrimp and sold locally in singapore a few years ago and since demand for it is low for these shrimp was not available for some time.

Recently shrimp fever brought them back and often in a bag of cherries you might find 1-2 of them i heard from a hobbist who bought from that local fish shop in singapore. There is also this fish farm selling these "black shell".

There are 2 variations of cherries i notice one with a pink stripe running down the back and the other without. Seems that these so called black shell also carry the variations cherries has but has a brown stripe instead with a brownish to black tint.

Reason: They do cross breed with cherries. The suppliers stock may have been cross with these "black shell". That is to say even if you have 100% cherry you might get 1-2 "black shell" offsprings but the chances are 1/10.

Despite its less attractive color, I heard from a hobbist they are mighty algae eaters like the amanos and to me they are a beauty too. But its best to separate these two if you want to maintain a pure cherry population or "black shellies".

I totally agree with you, those black shell shrimp which the taiwanese called them are actually offspring of the cherries. I had many of them in my tank now......

[Robert]

Hi,
these "black shell" shrimps cannot be offspring of the cherry shrimps because the cherry shrimps are a color morph of Neocaridina denticulata sinensis. The normal colored Neocaridina denticulata sinensis (and probably other subspecies of N. denticulata) are feeder shrimps in many parts of China, so you probably keep some of them. Their coloration varies a lot but is mainly translucent till brown or grey. Of course they can breed with chery shrimps because they belong to the same species. So I wouldn't keep them in the same tank if they are really "black shell" shrimps.

Best regards

Robert,

The so called Black shell shrimp although sounds to be black but it is not at all, it is at best light brown. It could be the feeder shrimps of what you said.

Since brown is the dominant genes, it may just take 1 brown form of Cherry Shrimps to make large population of Black Shell shrimp by crossing with Cherry Shrimp.

Hi Bro,

I am quite new to shrimp hobby. From the pic, I think they look like Malayan shrimps?

[gnatster]

Interesting, I wonder if it is worth my time to try and breed some of these and see how they come out. I'm just thinking outloud here and knowing me like I know me I'll probably keep working with these for a while to see what comes out. Thanks for the pointers.

Those look familiar. I have about 100 or more of those guys now, started with 10 of them 6-8 months ago. They are Neocardena sp. I from what I have been able to gather. They are great algae eaters and breed like crazy, they are a higher order of breeder so there is no larval stage. From what I have noticed keeping these guys is that their colors and patterns very a lot, depending on their mood. I have had some that went totally black with the light brown strip down the body, then change back to all tan/brown. I have seen them go almost totally clear to a reddish color.

They seem to be picky about water conditions especially nitrates, but in a planted tank with ~10ppm No3 they do fine. Over 14 ppm you may see a little die-off, like when one day i noticed the filter wasn’t working (wondered how long it was off for) and there were a dozen or more dead. BTW they eat their dead lol .


I have a few pics in my gallery here of them.

[gnatster]

Thanks, unfortunatly I lost them all. For some reason I ahve the worst luck with this one stores imported stock. Rather frustrating.

These shrimps come in different colour tones I have seen a few pieces that are very dark brown in a bag with light brown ones (in a floating bag in when I went there in my futile trip to look for cheap crs)
