leave the fish in. Take the decorations out and take a bucket of the tank water and just scrub them up. Then you can put them right back in. You don't have to do water changes so much. Once a wk is fine. You should get a test kit that test the ammonia when you go shopping again. Main thing is to watch your fish. If they start acting weird then something's up. And the slime coat is when your cycling the tank. Sounds like yours is past that if it's got a green color. vacuum the bottom. Don't wash it, just get the poop and wasted food out of there. Your fish will do alot better without all that in there. It becomes toxic if that build up just sites there. And in the future you might want to have another tank on hand, case you have to pull one out to treat it for something. Just to have it. A 10-20g is idea. Just because it's easier to dose medication. (Just keep it in mind)
