Looks like all the fish came through none the worse for wear with one exception. I did have one dead neon tetra when I got home. It wasn't decomposed or nibbled upon, so I'm guessing it died sometime just before I returned. The oscar seemed extra happy to see me. He was even more wiggly than usual and very happy to get fed.
The real excitement came last night. I was in the living room when I heard a noise coming from the room where the oscar's tank is. Seeing as how I've no pets other than fish and he's the only one in that room, I knew he had to be the cause. At first when I turned on the lights, I didn't see him in his tank. That sure got my adrenaline flowing. While trying to look between the aquarium stand and the wall, I caught sight of his tail sticking out from behind his flowerpot which is in one corner of his tank. He was still in there, thank goodness! His tank is in a corner. There's about 16 or 18" between the left side and a wall, which is the side his pot is on. I'd looked at the floor on that side but not actually into the tank so I didn't see him upon first entering the room. Looking in the left side of the tank, I discovered he was upside down with his dorsal fin just in the sand.
I reached in (foolishly not even thinking to wash my hand and arm first, I'll admit) and give him a little nudge on the side with a finger. He righted himself and very slowly moved out from behind the pot. Another little touch on his dorsal fin and he moved to the far side of the tank.
Looking around the tank, I noticed a few drops of water on the wall behind it and the rim of the tank and that the cover on the HOB filter was askew. (I have an Aquaclear HOB and a canister filter on his tank. I just like having backup in case one fails.) My best guess is that the doofus decided to try to jump out of the gap where the Aquaclear's return hangs over the tank. The plastic flashing on the tank lid is cut so that it's flush against the HOB so there's only that 1cm or so wide gap where the water flows back in over the lip.
I checked on him a few times before going to bed and again this morning. He seems to have scraped his head on one side, but I don't see any other injuries. He's usually fairly inactive by that time of night, so I'm not sure what possessed him to try to jump. I'd guess maybe he was going after a bubble or something on the surface, thinking it was food. At the time of the incident, though, his light had been out for well over an hour and the lights in the room were off.
I guess I should be grateful that the glass lid and weight of the stuff atop it kept him from actually getting out of the tank!
