Lastly I am enjoy so much with these little guys from seasonal pools near to me. They are beautiful on colours and behaviour.
I leave you some pictures.

Some shots from up side with white background.

Nice pictures as always Xema. You collected these from the wild?
If these are similar to Thai Fairy Shrimp, do they hatch like brine shrimp?

Thanks for sharing!

Very nice and interesting pictures.

Here in Malta we have Branchipus schaefferi.

Due to the loss of habitat and to the very limited number of vernal pools they have become very rare :(

Any other inverts in the pools?

This is a link to a visit at a local vernal pool where on can find some pictures of Branchipus schaefferi (fairy shrimp), Cyzicus tetracerus (clam shromp) and Triops cranciformis (tadpole shrimp)

I find very interesting the life style of Concostraca -clam shrimps-. There we can find some kind of giant copepods.

Hi Xema,

nice photos as always. :)
I, too, kept two different species of fresh water fairy shrimps.
They are very interesting creatures and I could spend hours watching them. But unfortunately they only have a very short life spawn and their eggs only hatch after they have been dried. At least the eggs of the two species that I kept, didn't hatch if they stayed in water. They had to go through a dry period to be able to hatch. That makes the whole thing a bit difficult.
What about your species? Do their eggs hatch in your tank or do you have to dry them, too?

Bye,

Peter

Really I am not sure, I am still studying that, But that seasonal pool stay full of water from september/october to may or june, and as I know all the time with water there are lots of fairy shrimps. That means they live the whole time with water, or there are few generation along the time the pool stays full of water.

What plants are those, they look extremely small when compare to the triop. Or the triop is giant?

What a sharp eye Silane ;)

The plant is Elatine gussonei, a beautifil plant that grows in some of the Maltese rocky vernal pools.

This cute little plant is very rare since these pools are extreamly few. Its leaves are even smaller than those of Hemiantus Callitrichoides.

Elatine gussonei eventually forms a thick green carpet.

Elatine gussonei looks much like Glossostigma elatinoides (note the latter’s specific epithet) but is much smaller, with leaves less than 1/10th the area of the full-sized Glossostigma.

The article was written by a big friend of mine who introduced me to this species of aquatic plant. It's a very interesting article and I'm sure you will find enough information regarding this remarcable cutie.

I will open a new thred where I will post several pictures of elatine gussonei.

Hi,

the dried eggs of the triops can easily be shipped.
There are several online shops that sell triops eggs, so it shouldn't be difficult to get those eggs shipped to Singapore, too.
To let the triops eggs hatch is as easy as hatching artemia. The difference is that triops don't need salt water. Distilled water is best to let them hatch. Later you can carefully add normal tap water.

Peter

Same happens in the pools that I visit. They usually dry just during May just like the pools you have in Spain. During the period during which they contain water there are always some fairy shrimp.

Could it be the shrimps produce 2 types of eggs?
Those that hatch after the dry period and those that do not require dry period (when water is plentiful)?

Hi,
as far as I know it depends on the species of fairy shrimp.
Some species really are able to produce 2 types of eggs exactly as you said.
It's also the same with most species of Artemia. They only produce duration eggs (cysts) when the conditions become worse.
But many species of fresh water fairy shrimps only produce eggs that need a dry period to hatch.
I kept an American species (I think it was Branchinecta lindahli) and Thai fairy shrimps. Unfortunately both species didn't produce eggs that can hatch without a dry period.

Hi Peter thanks for the prompt reply, this is very interesting, what's their lifespan like? Where do I order online, can u recommend a online place or can I order from triops.es? How much do they cost per pack?

Hi,

I'm sorry, but I don't know which online shop to recommend.
But there are lots of online places that sell triops. If you search "triops" on google you will find many. You even can get triops eggs on Ebay.

The life span of most triops is quite short, it's only about 10 to 15 weeks.

As I only know German sites with information about triops, I just looked at google and found the following site in English which makes a good impression:
http://mytriops.com/articles/triops_care.stm
This should answer most questions about these unusual critters.

Bye,

Peter

P.S.: I'd not recommend to keep triops together with shrimps. They will try to catch the shrimps.

Oh cool to handle by hand, I manage to keep only longicaudatus, for cancriformis and australiensis, they just die after a few days.

Any idea a why they die after 3 to 4 days?

MyShrimps
20th Nov 2008, 08:54 PM
Hi Silane,

well, I'm afraid that's difficult to tell from the distance.
And I am not an expert in triops at all. I only kept one single triops that hatched accidently together with my fresh water fairy shrimps. It was an interesting creature and I'm sure I'll have some again one day.

Your triops nauplii died just 3 to 4 days after hatching?
My experience with fairy shrimps says that the first week is the most difficult to keep the nauplii alive because they react very sensitive on nitrite and some kind of bacteria. And that's the same with triops nauplii.

Most people feed too early and/or too much.
The nauplii (larvae) are not able to eat anything for the first 2-3 days. So one mustn't feed too early. And when you start feeding it should only be a very small ammount. The food which is given but not eaten decomposes very quickly and deteriorates the water quality. Especially the ammount of nitrite rises and kills the nauplii and some kind of bacteria grow, which are dangerous for the small triops larvae.
In my opinion that's the most common reason why the little nauplii die during the first week.

But I don't know if that was the reason for your triops' death, too. There are many other reasons why they can die. For example: wrong temperature (T. cancriformis for example doesn't like high temperature), something in your tap water (chlorine or copper for example) that they didn't like, not enough unicellular microorganisms as food during days 3 to 5, lack of oxygene, too much current because of filtration or aeration, etc.

Bye,

Peter

Hi Folks, I need some advise.

Today is Day 14 since my Triops hatched and I've yet to transfer it to a bigger tank as I'm afraid if I do so the little fella will die on me. I just did some tests on the bigger tank (With mosses and Gex Soil "Red Packet") and a small hang on filter, the following are the test results

Bigger Tank
PH 6.4
KH 6
GH <14
NO2 0
NO3 10
Temp 22.8-24

Currently reading from its small hatchery
PH 6.4
KH 6
GH <3
NO2 o
NO3 10
Temp 22.8-24

the thing I'm worried is the GH difference, should I transfer the little Triops to the bigger tank? :bs_help:

Hi,
you can make it easier for the triops if you do some little water changes for a few days before you transfer the triops. I mean you take some (not all!) water out of the small hatchery and fill it up with water from the bigger tank. So there won't be one big change but several small changes and the triops should quite easily accustom to the other water values.

Peter
