hey i have a 30 gal wit angels and gouramis can i get a pair and breed them or will they attack the other because of the tank size. ive heard they get very agressive when breeding
Firemouths are not that aggressive, but like you say, even non-aggressive cichlids area aggressive to a point, especially when breeding. You can get away with a pair of them in a 30, but not with other tankmates.
