Hi all, I have a betta named Donald in a 5.5 gallon tank. I am thinking about getting a snail or two, however I am completely inexperienced with them. My tank used to be in a spot with almost no sun, and never had any algae. I moved it to a spot with a lot of indirect sunlight just 2 days ago and haven't had any algae. Snails eat algae, right? If I have none, what will the snails eat? Again, I am completely inexperienced with snails so any type of advice would be greatly appreciated. One more thing, I have heard of people getting a snail with eggs and having a real problem with the snail babies. What type of snail would be least problematic in this case? Also, do snails poop a lot? Would that be a problem?
