i bought a 29 gallon tank about 2 months ago let it fully cycle and have added the fish i wish to keep. 3 small kribs (2 females, 1 male) 2 small jewels(1 male,1 female), 2 small blue acaras(sex unknown) 2 medium convicts( agian sexes unknown) and 3 tiger babs. i have added as many rocks and hiding places as the tank can hold.However the larger convict has taken control of the tank and has began to bet up the other fish the smaller acara in particular, most of the fishes fins are getting nipped pretty badly is there anything i can do to prevent this in the future and is there anything i can do to help thier fins grow back
