An adult female Caquetaia umbrifera , note that holes in the divider allow passage by the female but not by the larger male. Secondary sexual characteristics in C. umbrifera include a slight nuchal hump, larger size, brighter markings, and extended fin filaments in the male. Photos by Jeff Rapps. Caquetaia umbrifera is easily fed, readily accepting a variety of floating pellets, freeze-dried krill, and earthworms. However these types of foods can be detrimental to the breeders by possibly introducing unwanted parasites.
Clean water is essential for good health.
I thought the pair would spawn inside the tube, but the female has always chosen to lay eggs on the outer wall. Once the pair successfully spawns, vigilant care of the eggs and fry is a delight to observe. The female remains in close proximity to the egg plaque most of the time, while the male patrols the peripheral areas of the tank. Beware, as these fish, when guarding young, will even bite the hand that feeds them. Though the female is especially pugnacious, I find that if I need to change water or move something inside the tank when eggs or fry are present, the parents will eventually back off until the commotion ceases.
