Feeding Shouldn't be hard to feed. Eats insects, insect larvae and even detritus.
Breeding Males build floating nests in vegetation near shore that consist of bubbles covered with plant material. Eggs are released by the female below the nest. The male fertilizes them and then takes them into his mouth and blows them up into the floating nest. Breeding males develop enlarged, red pectoral spines with hooks at the tips that are used to defend territories against other males. The eggs hatch in about four days.
