Well I thought I was doing good. Of my four GBR's I picked up from big Al's I still have all four...But that might not last much longer. One of the females is swimming vertical near the surface, and doing a bit of gasping. Her stomach seems a bit distended, but not hugely so. No scales standing up, but she does have a slight tear in one of her anal fins and her third spine on the dorsal fin appears to be nipped.
I didn't think much about the nipped dorsal because it was there when I got her, and it's just a tiny bit of the tip.
Well so much for that, just went to test the water before doing the water change and she's gone. Tests all look fine, ph7, nitrates 5, 3kh, 8gh and no nitrites or ammonia. The only fluctuations I've had were the temperature dropped down to 78 during our cold spike here in south Florida. It's back to 80 now, and usualy sits around 81-82, wich is why haven't bothered with heaters.
