Do they need any land, can they live in an aquariuam, will they catch pet fish with with that intimidating claw, how big of a tank do they need, are they freshwater, and what temperature do they need?? Thanks!!!
They do need access to an area above the water line and a way to get there. On the other hand they are escape artist. I had mine with small tetra's and he never got one. They do need brackish condition... Something I found out to late due to lack of research. 74 - 78 give or take on the temp.
