The Red Tailed Shark is a tricky one at that to breed, they are violent to their own kind and will hurt each other. so far i have 4 separated and when all four's health is at 100, I will put them in one tank and hope for the best. they are extremely hard to mate, but I hear its worth the hassle. I keep their filter no more than 10 percent dirty and do a weekly 10 percent water change with chlorine cut.
