I've found a small diversity of fish that i have now, and plan on keeping more of similar fish in the future. They are spread out between 3 tanks (5, 10 and 20 gallons). I've been debating on getting some of the Xtreme fish food after hearing so much about how good it is, but I'm not sure if there is a 'one size fits all' for my types of fish. Any advice would be helpful. Currently they are getting mostly flake food and bug bites and I'm sure it's not the best option. (occasional frozen blood worms)
