I was very lucky with my hatchlings. I have 2 female banded bamboo sharks that I bought from eggs since that is all that is available around my area. After hatching I waited 2 weeks before the first feeding and on the very first attempt I had both sharks eating and the rest is history. I did my homework before I jumped into keeping sharks and maybe having the knowledge on my side is what led to my success. They are growing very quickly wth 2 feedings per week of a varied diet of fresh seafoods. Once they start to reach the 2 foot mark I plan on upgrading to a 300 gallon custom tank. The only tankmates they have are some hermit crabs and a large marine betta. They all get along very well. The new tank will have rounded inside corners just like the 180 they are in now that I bought from Tenecor, it's an acrylic tank and the corners look awsome.
