If i added 3 more in one go would they have to be the same or could the be different that would put me up to 15 would i be ok with this? i have 2 filters running on the tank
You would still have exactly the same problem, the new fish would almost certainly get picked on, in this case especially by the other fish of the same species. There is no easy way of adding a single fish to an established tank.
I was looking at another o.b there is one that looks different its white and orange with dark bits was thinking of him but would i be best getting 2 other different ones aswell.
The man in the shop told me i could keep this in a mbuna tank he seemed to be doing good in the tank he was in but i wanted to do some research on what it is and where its from or more to the point if i can have it so whats its name?
