Hello. I asked one other question and everyone was very helpfull, so I am sure some one will be able to help me with this. In my 90G, I have 12 fish now, They are all african chiclids, but as far as types, I only know I have (02) Frontosa, the rest I am not sure about so if you see any in the pic that you know the type, please let me know. I would like to add more, but don't want to over stock. what are the recomendations for this size and type of fish as too how many I should have. Thanks in advance for your help.
