I have a 10 gallon tank with a betta, 2 mystery snails, and 3 african dwarf frogs. I feed frozen blood worms. I tend to over feed a bit that way whn the betta has had his/her fill, theres still plenty left for the frogs. I also throw in an algae wafer every other day. The snails love those. I dont feel like they're getting enough variety though. What else should I be feeding them?
