Hi I just recently purchased four 2in MiDevil hoping to get a pair and a cichla (not sure which the guy said ocell but didn't sound sure)2in also.The cichla is in a 30g by himself and the midevil are in a 30g also. My cichla is doing great but on the other hand there is one midevil(my fav of the bunch) that consistently gets harassed by the rest. Would it be OK to move him with the cichla ??
