Ok so i wanted to know how large your guys' chalceus grow as im getting conflicting info online, some places say 8-10in some say more like 12in (not big difference i know just wanted to see what was more realistic) also was planning on getting one to be a top level swimmer in my 5ft 120g tank (will have carpinte pair, female festae, and male GT for cichlids and then IF it works out a BGK for the bottom) so from what i read it said they do well either alone or in groups of 6 or more, so was planning to just do one because i definitely dont have room for 6 but wanted to get your guys opinion on if they could be kept in smaller groups so the chalceus wouldnt be by itself with the aggressive cichlids (or will it be fine by itself) anyways was thinking if they wouldnt fight to much to get 3? would this be ok
