Microworms and vinegar eels. Come spring and the availability of grindal and white worms, I'm going to get those but for now I'm ready when I get fry. I'm out of brine shrimp eggs and have to get some. $50 bucks a pound now ! Oh well, that will last quite awhile.
Wow ! They look great ! Yes, what you say about less water pollution with live foods is something I've read from several sources lately. One Killifish breeder says he uses no filtration in his small tanks because of his feeding live foods only. That and daily water changes. I would really like to take a shot at culturing daphnia next spring. Everything I read says that daphnia really take your fish to another level of health and vitality.
I've been doing a lot of reading on culturing daphnia. It doesn't sound too hard but I might need more space than I have. She Who Must Be Obeyed is beginning to grumble about all this live food fascination and is voicing concerns which are not worrisome but try convincing her.
