If I knew what this stuff was, I would be able to research it in FishLore. But, I don't...help! I have a fresh water tank with platties, frog fish corys etc. I have live Java Moss and artificial plants. This is a 50 gallon tall tank. On the artificial plants, I see mounds of greyish growth that looks like catepillars / or those fall wooley worms. What could it be?
Am changing water now and taking plants out to scrub. Not sure if they are harmful? Tank has been set up for over a year. My
ammonia levels are high - 1.0 / Nitrates and Nitrites are normal. I've slipped in keeping tank maintenance - changed water about a month ago.
Any help / input is appreciated.
