Fed everyone. It looks like the otos found the new lettuce or the current made some get caught under a java fern. They aren't eating it right now, so maybe it was just the filter. Mr. Fish seems to have stopped his aggressive, territorial displays towards them.
One of my new plantlets is losing a lot of leaves. I'm going to move it to an area with more light. The rest of them don't seem to be doing it, so I'm guessing it's the lighting situation.
I agree that Mrs. Fish will just have to live with her algae. There are just a few spots on some of the silk plants so far. That's how Mr. Fish's started, though. I'm going to cut a couple hours off of her light to see how it helps. The worst parts are ones facing the window, which lets indirect sunlight to her tank. I put some paper in front of the spotted leaf to see if that blocks enough light to it. I might get her a moss ball; I'm just afraid the light in there is too dim for one.
