I recently got a ton of new plants... I placed a bunch of wisteria under the filter outtake just to break of the flow a little more (it's also baffled). Mr. Fish has take to sitting on top of the wisteria so that he's under the outtake of the filter, and can't be pushed down. He then stretches his nose up and pokes/bites at the sponge from the baffle that hangs in the water. He also pops the bubbles that collect under there. In the past 3.5 months he's never had an interest in the sponge! Lol. What a weirdo.
I'm going to try to snap a picture next time he heads up there.
Anyone else have a weird fishy?
