Should a golden striped maroon clown have another golden stripe maroon? I have a BTA in my 125g ans want to know if I should have 2 clowns? Will a clown fish live without another?
It is a personal choice, if you decide you want another GSM, make sure it is smaller then the one you have. Hopefully, after some squabbling, they will become a mated pair.
I always have 2. I'd go a little farther than to just say smaller than the one you have, it should also not be the biggest in the tank at you LFS. If your is already female and you add another female, it wont work. They do not turn back to males.
