I imagine that would be a pain to deal with snail goo, but I here its also a pain to have a snails overpopulate your tank to.
I dont have any bettas yet but I like your recipe and I will probably do brine shrimp and blood worms a couple times a week. Im not sure what to do about fry food BBS seem like alot of work so I was thinking vinegar eels and some kind of worm. I still need to do a little research on the fry food.
