Hi all, well I'm back - went away for a couple of weeks and had a great time. Got back and found my community tank infested with 100's of snails . What fish can I put in to get rid of them. I have 2 gobi dragons, a large pleco, a male betta, various platies and mollies and 6 corys. The tank is a heavily planted 180 litre. The only fish I can think of are clown loaches but I'm not sure if they would get on with the other inmates. Advice please
