well had one of my red plecos die this am. the rest were doing ok and I tested water everything was fine so prob just bad heart. guy gonna replace him this spring with a long fin albino when they grow enough.
then tonight had an emergency I made new batch of CO2 for my bottles and it started pumping out then few hrs later I noticed fish at top of tank gasping for breath. I raised spraybar above waterline to break up the surface more and release the gas and changed abt 15% of the water and they seem to be doing fine now but it was a scare.
