Hey all I'm new to all this so was wondering if anyone can help? I have a 35litre (9-10 gallon) tank with 8 wcmm and 3 platys, 2 platys are fine and swim round together yet the other one has started to bully the wcmm and has even started Nipping at their tails causin one wcmm to lose most of it's back fin, will this grow bk? And will he survive?? Also why is the platy doin this?? Thanks for any help
