I breed them in my 3 ft. Well, not so much as breed, but feed. The daddy goes into his home, then babies appear. About 4 days after he comes out of his home, he goes back in and has more babies. I've had 4 sets of fry since March 18, after 2 years of no babies, no matter how hard I breed them. I don't take the babies out, except ones I get rid of.
