I feed them every day. You could probably feed them every other day. 1-3 worms per depending on size. My guys are still pretty little. I am not concerned if any stay on floor. I have some dwarf crayfish that cleanup or the DP will later on. Plus if they are still hungry they can snack on the snails that are in the tank.
I apologize that I did not see this before. For some reason this message did not show up on my phone like a private message does and I have already sold the packages. I should have another package available next week if you are still interested, though some of the plants available may change. Please you the private message instead of writing on the wall next time so that I definitely get your message. Thank you for your interest!
They recommend 3-5 gallons per fish. Heavily planted tank as well. Having snails in the tank shouldn't be a problem. They will stop eating when they are full. I usually put a bunch of snails in and feed them live blackworms as well. They don't really need snails as they dont have a tooth like other puffers but they still like them and will eat the snails by sucking them out. Hope that helps. Live or frozen food... they dont like the flake foods.
