So after recently losing my pleco that I had in my tank for years, I came across some giant apple snails at my lfs. I was thinking that it might be a decent way to help keep the tank clean and add an interesting element to my tank. I'm trying to figure out though if my fish will just eat it if I get one. The ones I saw at the store were baseball-sized but I have a clown knife and an arowana that are both in the 2 ft range as well as an 8" pike cichlid. What do you guys think? Will the snail just be a $6 snack for one of my predators or do I have a chance that this thing will be able to make it as a new addition to the tank?
