trying to get a mated pair of bangaii cards. i had 3 in my breeder tank. all males one was killed and i moved the smallest of the 2 remaining to my 10 gal reef tank. if i try to get 2 females. could i put a second in the 10 gal or would that be too many fish. it is a 10 gal w/5 gallon sump and only frags. the bangaii in there now is only 1-1 1/2in. if not i will put them in my display.
