I recently got a tropical fish tank off of craigslist. There's two black skirt tetras, one white tetra (might also be a skirt), and one guppy. All 4 recently had ick. The three tetra get along well but the guppy is making me worried. He was at the bottom of the tank when we got him but he still swims around to eat. Is there anything I can do to make sure he gets better? P.s. We are doing a 30% water change after I get a response. I also have money set aside to buy him a school. Thank you!
