Moved my Red crab over to my new 160l tank (was in 60l). Also got 2 guppys, 3 tetras and a pleco in there.
Not sure if one of my Guppys was ill, as he has been swimming around just fine (like a few hours ago), found the crab eating him tonight!!
I been watching the crab and seems to be hiding and waiting under the new rock setups, seems more like he is waiting and will come out if I lift my hand near the rock from outside, never seen this in the old tank.
I hadnt read up much on red crab, and he seemed ok (only been a few weeks in other tank) but not sure if this thing intends to eat the other fish, or whether the guppy was ill and got eaten! Any comments?
What did you think crabs ate? Small fish (especially slow swimming ones like guppies) and crabs do not mix well. I'd re-home the crab as soon as you can because he will eat the fish if he can catch them and he seems to be able to get the guppies pretty easily.
I think the new tank setup lends itself moe easily for him to prey as it has higher rocks, more areas for the fish to swim through where 'pinch' can hide. He has gone back in my gourami tank but they are breeding so cant stay there long!
