Hey guys, first post here so plz go easy...lol. Anyhow, i was wondering if it'd be alright to put red clawed crabs with cichlids together? I was planning on building a 3D diy background and i'd have the top, instead of it reaching the top of the tank, cut it a few inches short. There'd be a natural looking shelf above the waterline for the crabs to climb out of the water...just wondering if it'd work out or not... Comments and suggestions welcome..
