I know that there needs to be more than 1 ADF in a tank but I am wondering how many ADF's would you recommend putting in a 10-gallon tank? I know I want to put a few snails and guppies in the tank as well.
You can do just a pair if you don't want a bunch of frogs. 3-4 may be ok if it's with fish. Just make sure they are getting food, I hear that they are lousy at actually finding the food and can starve if the fish eat everything before them.
