I know they are common but I actually like convicts. The problem is you rarely see high quality ones. Out of the three years I have been back in the hobby constantly looking at fish at tons of stores, I have only seen what I would call a quality fish three times. Bought one of them and it was killed by aggressive tankmates. The other I passed on because it was small and did not have room. The third is one I am raising now. Great looking male with long trailers. These guys are easy to breed but someone needs to breed nice looking ones.
