It came right to the surface, kinda looked like it was trying to suck on the surface(so it was upside down), seemed to have trouble swimming balanced(it was more crooked to the one side) plus it's tail was bend lot more to the left, and the general coloration was not totally normal I'd say. Almost kinda looked like it was having a seisure.I added on another bucket so I could turn on my smaller filter, in case it was lack of oxygen. Then I didn't see the little one anymore and filled up the tank as usual. I spotted it again later on the evening, still alive and breathing, but it's quite skinny and still seemed to have little issues swimming, but not as bad as before. Now this morning I've yet to locate it.
I think the same fellow has been acting that weird for slightly longer period of time, but nothing that would cause major concern. Just doing things the other ottos don't do, like suck on the filter's cord.
Any ideas?
No external injuries, I'm 100% sure I used water condition on the first bucket. Only thing that was different about that first bucket is that the water was warmer than usual. But not too warm I think, but I usually add tad colder water than in the tank(temps might drop a degree or two) and it's a fact that warm water contains less oxygen... I highly doubt there's anything weird on the water parameters either... Or at least if there's something weird, I don't have the test for it(like copper, chlorine etc.).
