I don't know of anyone in the USA. but they seem like wonderful snails. I've seen the topic a few times in the past. Try the searce for Theodoxus fluviatilis and see what you get.

None that I keep or know that anyone else keeps. O2 in the water, but not access to air.

There are species that build mud cones and spend time above the water line, but this does not appear to be a requirement. They have gills and not lungs.

Access to air doesn't hurt, but they don't need it. They do need air in the water. A species ID would help. Some crays can spend quite a while out of water as they go from one pond to another.

You should go read the articles and do a little search for this info. Have another look at the rules before you get warned or banned. This question has been asked & ansered a bunch of times.

Neither. The mating should occur before the berry, but the berry can happen with no fertiliztion. She'll drop the eggs in a few days if they are not fertile.

Electric blue generally refers to P. clarkii or P. alleni. Most other blues are Cherax species.

I don't know what species I have, but they get to be about 1/2". Got them in my local creek last fall along with some water louse.

Be carefull as some may be under pressure and you could be hurt. Wear eye protection.

Ah! Thanks. I've only seen them referred to as Gammarus with no species name, while with daphnia it is quite common to refer to pulex, magna, etc.

They will interbreed.

My experience in the woods has shown me that oaks take years to decompose in nature. Your shrimp are eating much of the leaves in your tank. There is a big difference between dried leaves on dry ground and nice and cold in the north-woods of Michigan and a tropical pond. The break down of the leave...

Semantics. Rotten leaves implies that the leaves are rotting. Fallen brown leaves do not rot right away especially oak leaves that so many use, it takes oak leaves years to rot in nature. You are incorrect about this entire response. Until you have tried it, do not make things up just because you t...

Fishguy-
If you knew the answer, why did you ask? You must not use much sand. No substrate is still the best.
