Hi all. Yesterday I got Buddy a heater for his 2.5 gallon. He had been fine and happy prior to this but everything I read insisted he needed a heater.
He hated it, and spent 1/2 the day yesterday flaring at it. Last night he seemed to get very lazy,spending a lot of time just hanging by a side of the tank...I just assumed he was tired, but I removed the heater just in case the water temp change was too much.
This morning he was floating on his side.
Alive, though. He'll swim around if you prompt him. I removed him from his tank and put him back in the cup I got him in and he has remained upright in there.
WHAT DO I DO? Just wait it out?
