I had a breeding group of 4.6 White Spotted Bamboo Sharks in a pond 8 feet x 2.5 feet x 1.5 feet deep.
After 3 years on a diet of chopped capelin/herring/smelt, scallops, and clams they started breeding. Over a 3 month span I got over 120 eggs from the group, of which ~90% developed.
Nothing special for care, standard day night cycle (lights on at 8, off at 8:30), housed on sand with hides for the adults. The females like to have structures to lay their eggs on. Incubated the eggs and babies in a separate tank. Took about 3.5 months for the eggs to hatch, but they were kept on the cooler side(21-22) during incubation, but I'm sure if you kept them warmer (around 25-26), they would hatch faster.
