I just thought I'd let everyone know I just picked up a Weather Loach for my 30 gallon cold water tank, which as 14 Rosey Red Minnows in it. He seems to be doing well so far, already has started eating. I fed the Minnows some bloodworms not think the loach would think about eating them yet, but sure enough he loved the blood worms. The only thing I'll have to keep in mind I guess is making sure he gets food, as the Minnows are aggressive/active eaters. I'm hoping to get a hold of some small earth worms to try on the Loach.
