One of my otos died yesterday. Idk how though, his belly was full and I had just changed the water last week before I left for home.
I did a almost full water change, and finally got the baffle sponge inserted while I was at it.
I ran everything under really hot water, but I don't know what else to do. :/
I think he may have died because my heater is on its way out the door, when I went to change water yesterday the tank was at 71. It can barely keep the tank at 76 now. ):
Gotta go buy that new heater sooner than I thought!
