Stompy8 Posted March 29, 2020 Share Posted March 29, 2020 My nano tank is a few months old. This started growing from about the size of a pin head. Now it is about the size of a dime and I saw it move for the first time. It’s been stationary since I first noticed it maybe 4-6 weeks ago. Quote Link to comment
