seangtat2kc;2297682; said:I have lost many fish (jardini, electric blue dempsey, figure 8 puffer, 2 clown loaches, 2 golden nugget plecos, bristle nose albino pleco, ect.) to bad heaters. so i stopped buying cheap heaters and all i use is stealth heaters which are guaranteed not to break. I have had no problems with heaters since.
