HI
Thanks for the quick replys
Ha OMG I have just looked @ the thermometer and I have read it wrong (only got it the other day) the temperature at the moment is sitting @ 86 and that's after 50% water change so ummmm yeh it was high!!!!!!
Around 90!!! The tap water itself really doesn't seem much cooler......I could start to add ice but that will certainly keep me on my toes.......and no, no
heater.
Think I may have answered my own question!!
Like I say all other fish seem fine it's just the guppies in that tank that are dropping on their arses, oh and the peppered cory that was fine one minute and then I looked back about 5 min later and he was dead. I have looked him over and his colours are gorgeous and no sign of any disease......so must just be the heat.
I had the same problem with my heater a little while ago. No matter what temp I set it to it kept the water at 90 degrees F. Quite a few fish deaths and some serious evap problems.
