CO2 bubbles on fish?
Can the white dots be CO2 bubbles instead of Ich?
I apologize in advance for the lack of pictures.
I have a 90gal, CO2 injected, planted community tank. I bought 3 Irian Red Rainbows 3 weeks ago. (no quarantine at the time) I noticed they had lip rot and treated with MelaFix. That took care of that issue after about a week. Doing weekly water changes, all water parameters are good.
About a week ago, I noticed what appeared to be Ich, only on my 3 Irian Reds. Figured that made sense. If they had lip rot, they were susceptible. Dosed tank with Ich-x, daily water changes. They have become more active. Eat well. But the white spots are not going away, but getting more abundant. Finally I threw together a 20 gallon quarantine take to isolate them and run salt and cure-all meds. But as soon as I transferred them over, I could no longer see any white dots. Like not a single white grain on any of them. Granted, I am using differently lights now. Crappy fluorescent instead of full spectrum LED. My wife suggested it could be the CO2, since they hang out right above the diffuser. Could that really be the cause and I have been treating a 90 gallon tank for Ich for no reason?
