Temperament: Generally peaceful, but can be aggressive eaters and may become territorial while breeding.
Diet & Nutrition:Usually very good eaters, they will take flakes, pellets, freeze dried (re-hydrated before feeding to prevent bloat and other issues - blood worms, brine shrimp) and especially live foods and fresh veggies.
Breeding & Spawning: Will lay the eggs on a vertical or diagonal surface. Assuming you have a pair, they are not difficult to breed.
Gender: No visible differences between the male and female except at spawning where female has a round "tear-drop" shaped breeding tube and a male has a cone shaped breeding tube.
