Large Red Mithrax VS Melanurus

[DocRose]

I have a huge red mithrax crab (two actually) in a tank I used to QT ocean live rock for hitchhikers. I’m wondering if I move them to my DT as part of the CUC will they be able to fend off my melanurus? They really are big. The biggest one has a body almost the size of a half dollar coin and claws almost 2” long. My melanurus has already taken out half the snail population (which I’ll replace with turbos) and he’s about 4” long.

No idea, but I'm curious and happy to bump.

It’s a 50/50 chance. You may manage it if you can get the crabs as close to the rock as possible but also keep the Mel happy. I have a 2” sally light foot crab in with my 4” Chloropterus and 4.5” Iridis. It’s really just luck of the draw.
