| Behaviour | Not observed, but cave spawned. One day I looked in the tank and saw dad guarding a pile of wrigglers that are almost all out of yolk. Yay! At the same time, dad was trapping another female. They spawned 5 days later. Update: since the original spawn, there have been five or six more. One spawn had 16 eggs. Another spawn on 18-Aug-2018 had an egg mass of 18 eggs and one loose egg. The most recent was 22-Sept-2018, with 26 eggs. | |||||||||||||||||||||||||||

| Fry and juvenile feeding | Since I didn't witness the first spawn, the babies stayed with the parents and must have scavenged off their parents' food. In the second and later spawns, wigglers were taken from dad's cave and added to a fry net/basket. They were fed a variety of foods: Freeze dried blood or tubifex worms, Cobalt spirulina flakes, shredded raw sweet potato, and live black worms. Juvies were kept in the fry basket for the first 3 months of life. | |||||||||||||||||||||||||||
