- The red color on the throat is darker in case of a male. Firemouths
are very prolific breeders. Just wait. One dominant pair will get to
gather and will start cleaning one of the stones in the aquarium.
According to my experience thay prefer large ( >4" dia) smooth round
stone. Take out others and let this pair have tha whole tank. Feed
them properly. Rest fish will do i.e. laying eggs and rearing fries.
