My little guy is hanging out next to a plant at the top of the tank. When I came in this morning he was swimming around, and he's swimming around now, too, as I write this, but for most of the morning he's been pretty chill. Sometimes he'll just sit at the bottom of the tank, too.
He's a crowntail, and I've noticed that his fins aren't nicely splayed out like they are in so many of your avatar photos. Sometimes he'll spread them out, but mostly they seem to be closed up. I wouldn't say clamped, but not full, either.
Anyone have any thoughts? He's in a five gallon tank, water temp 78, filtered. I did a 50% water change on Thursday last week, and am going to do a 25-20% water change in a couple minutes. Also, my test strips are missing! Who steals test strips, anyway?!?
