I have a breeding group of 10 adults in a tank with a few brown banded and white spotted bamboo sharks, two bonnetheads and an atlantic sharpnose shark. 20'×4' pool, with a sand filter, bio tower, and carbon filter. I keep them at 74*F. They produced nearly 100 eggs for me this breeding season so far. The eggs take around 3 months to hatch. the babies and eggs are hanging out in floating rubbermaid bins with a bunch of holes in them, in a 300 gallon pool that i made the filtration on.
