So, a few things... First: I have a 5gl aquarium with 3 ADF and an apple snail. This apple snail must be lazy. Algae is overrunning the tank! The walls of the tank are getting more and more green bloches on it, and my snail spends most of his time clean the rocks not the walls... any way to encourage him to clean the glass? If not, what critter could I add to the tank that would clean it without running over the 1 inch of fish per 1gl rule? Second: I have a 3gl tank with a moss rock, and 5 adult pond snails, and about 50 baby snails. Would getting a betta for this tank keep the pond snails in check, and be a healthy environment for the betta? (I had a Betta before but I cept him in a 5gl with a filter) Third: In my 10 gl tank I have 2 kuhli loaches, a zebra snail, and 3 ghost shrimp. Would adding a third Loach be to much for the tank?
