It kind of looks like a digger crayfish species. The abdomen is rather small compared to the body

Yes there were some changes in names recently. We did not invent them, the scientists did do the changes. N. denticula sinensis is now N. heteropoda and Cardina japonica is now C. multidentata. Little is know about the babaulti group. The mentioned species all show the signs that make them babaulti ...

I have witnessed shrimp eat live and healthy mystery snail babies. If it is enough shrimp I think they can harrass another critter to death and eat the dead critter. It just dies of stress as it cannot escape the shimp horde. I also do not think that they can make an active kill. How should they, th...

I saw some in Germany too, once. But I would not be sure, that they are legal. Maybe they were just imported and bred without permit.

I have heard of cherry red shrimp eating adult Procambarus clarkii. That were thousands of them and few feeding. They were just starving I guess. Shrimp are oppurtinistic feeders that will feed on anything available if food is rare. So give more food to your shrimp and your snails will not be bother...

looks like a Procambarus. Alleni could be. That last one however reminds me of a Procambarus acutus I once had. It had the same fine black dots on the carapace. Any definite answer would need a close look at the gonopods of a form 1 male.

The research in genetically modifying crustaceans is not very advanced. Your egg-taking method would not work, because you need not-yet fertilized eggs. As soon as they are on the female shrimps body it is too late. I have read an article about crayfish. Here they cut hole in the carapace and inject...

Being in Germany does not necessarily mean you can buy all these shrimp. The rare species can often not just be bought in the petshop round the corner, but one has to know the right people etc. And a lot has changed in the last 1,5 years, many new species were imported / bred. Yes, I also hope I can...

I had these many years ago. I do not know the exact species. But I do know that they are not the young of a larger species. There are many species of ramshorn looking snails just in Germany. Maybe hundreds all over the world.

I do not think there are that many shrimp or crayfish species that actually will crossbreed. If you keep aside the color morphs and type localities of one species of course. What will be the gain anyway? It will not produce new colors. For that you will have to wait for a mutation (or increase the c...

Do you consider that crayfish blue? Nice dark color, sure, but blue? Maybe it is just me, but I think blue looks different.

Re: Dwarf Orange Cray/Brown mating right now!

Hey guys, My dwarf orange female is matting with my dwarf brown male (he is carrying the orange gene). This SHOULD result in 75% orange and 25% brown offspring! Actually, according to simple mendelian genetics (which is what I think we have here), you should be getting 50% pure orange crayfish and ...

Maybe Fallicambarus fodiens. But a 100% answer cannot be made by a picture.
