Does anyone know what the name of these animals are?

I am going to be setting up a fish room to breed fish and inverts. I am going to be looking for an animal that looks like a cross between a crawfish (the heaad and front look like a crawfish) and the back looks like a crab. They live in central America and do not get very large. I think that they would be great aquarium inhabitants as they are not supposed to be aggressive to other inhabitants or plants either (I could be wrong).

These fish are commonly called "Discuss". they looks very awesome. but if you keep them, you have to maintain the temperature of the tank by a thermostat. because these fish cant tolerate temperature fluctuation.

These are not fish but are closely related to crabs and crawfish/crayfish. I know what discus are because I have had a breeding pair of them before. These animals do not require the warm waters that discus do.

Can you post a photo so that everyone could see and help you in identifying that fish? Where did you saw the fish, the pet store? I'm intrigue cause i haven't seen a fish that looks like that.
