When I woke up today, he was hanging out under the filter, trying to attack his reflection.
I turned the filter back on, but he stayed under it, with his gills flared. So, I turned the bubble bar back on and he finally got outta there.
I left them both on all day. He would either get under the leaf of a plant to rest and stay in one spot, "lay" up against the corner opposite the filter (where the current would push him), or lay on the bottom, wrapped around one of the small plants. When I tried to feed him, it was difficult for him to eat his food, because it got moved around by the current too fast.
So, i set out on a trip to try and find something to block the current from the filter from part of the aquarium. I thought I might have to go to the hardware store and get a piece of plexiglass, but I actually found a solution at Petco. I bought a piece of glass that is supposed to be used as part of a lid (it's 2.5"x12"). I stuck that in the aquarium and successfully blocked off a corner for him to relax in.
He can still explore the rest of the aquarium, whenever he wants, but the current at the top of this area is almost completely still now, and he can eat without any problems. I may leave it, or I may try to take it out later...I'll see.
By the way, I'm rather upset at Petco! They have had their fish tank area closed off for about the past week, because they were redoing the floor (not sure if something had been leaking and ruined it, or what). Anyway, they had signs posted, stating that they would be selling fish again on Monday. So, I was excited to maybe get an addition to my tank while I was there today, but it's STILL closed.
I wanted to go buy fish elsewhere, just in protest, but I was too lazy to make the 20-block trek to The Fish Store...
