Final Notes
These fish school naturally in groups of twenty or more, so the bigger the shoal the bolder and greener they become. Add only to a fully cycled tank and keep temperatures on the cooler side. Egg-scatterers with no parental care; females are deeper-bodied and larger, males more compact and intensely coloured. Over dark substrate the green is unlike anything else in the hobby.
