I need to purchase a filter, but I'm not sure what I should purchase for Herman's tank. I'm looking for something that's not going to be loud or of bad quality. The tank is a 10 gallon. Could you suggest some filters for me? If you can, it'd be nice for you to add what the price is and where I can get it from.
Oh, I almost forgot to add that I don't want it to be too powerful for Herman to swim against because I don't want to deal with baffles. I'd hate to seem picky, but I'm not that good at building things.
