I'm thinking about putting a dozen WCM in my 30 tank. I'm keeping them and my lfs is selling them for 12 for $2.49. They are used as feeders, but a lot of people come in to buy them as pets. They are healthy and disease free. I was also thinking about breeding them. I think they might be compatible with my Goldfish, but I don't want my Goldfish eating the WCM fry. I guess that's why I have a spare breeding tank, huh?? lol!! Does anyone have any experience with Whit Cloud Mountain Minnows?? Any advice would be lovely!!
