Sorry. I posted recently about floating upside-down ryukins after
feeding. One of the suggestions was to raise the water temperature,
because I didn't have a heater in the tank. (Thinking, as you suggest
here, that my goldies didn't need one.) That's when I put the heater
back in the tank, and this happened. It's a fairly new heater, but one
of the reasons I took it out of the tank in the first place was that I
found it unreliable. (Always ran higher than I had it set for.) But
nothing like this last episode. Brand name on the heater is "Theo".
(Hubby picked it up fpr me when I asked him to, I didn't buy it
myself.)

Oh, and the fish did seem happier and didn't float as badly when the
water was warmer.
