Picked up my first 2 polys about a month ago. Regular sens. But was curious if its normal that about 90 percent of the time , if they arent looking for food, they chill at the surface in a clump of floating hornwort
Some poly will do that when you have floating plant, especially when they are small, they feel safer on top hiding inbetween the floating plant. Do you have other fish in there with them?
mine are active all day. make sure theres room at the top for them to get air. make sure you don't have any holes they can escape through in your top. welcome to the sickness!
