I have a few in one of my tanks, but they're all still small. The hatchery where I used to work raises some every summer and a friend that works there gave me around a dozen little ones to use as feeders. I split them between my 2 turtle tanks and my two aquariums. My oscar, sev, and bahia red had them gone instantly, and it took my turtles a week or two to catch all of them, but in my other tank my little Uaru of all the fish in there was the only one to eat one.
It's now been a month or so and they have doubled in size. There are at least 4 left and they are getting some really nice color on them. For now, they are pretty entertaining and keep the sand pretty clean, but when they start any real problems, they either get their own tank, or they're turtle food
Man you're lucky! I would love to have one and I just can't seem to find them anywhere! Would you be willing to let one go?
Also you have any pictures???
