i was reading the posts and thought that everyone might like to know my heater story, i went off on christmas vacation for around 4 days had a 55 gal bowfront and one big heater. well there were two oscars in the tank one reaching 10
inches and one reaching 8 1/2 well when we returned the heater was in peaces and the fish were acting strange. i didnt do anything to envoke this either before we left i gave them 50 feeder fish and shut the hood checked everything visually and left. now after cleaning out the glass and stuff and doing a 50% water change, they died after about a week. this was a few years ago and im not sure why any of it happened but it did and to this day i have no idea why. just wanted to let everyone know..
