i have 2 clowns and some other fish in a 93L tank and they have been in for 3 months now and a couple weeks ago i got a blue tang for the tank and they where fine and i have been thinking of getting 2 more clowns and i am not sure if they will be fine with it or not they will get enough food and such so will they be fine with it since they have been happy with the other fish and do not mind them even though they where the first in the tank so will they be fine with 2 more?
