I've had this big angel in my 46gallon planted for about 1 year. He has grown from smaller than a dime to large than a silver dollar. Usually eating everything in site and harassing another angel I have. The last few days I noticed he looks kinda flush almost with a red glow. He's a marble angel. I especially noticed red where his pectoral fin meets the body.

The only thing I've been doing differently is adding co2, but my kh is 3 and ph is 7. Any ideas.

What is your other levels? NitrAte and ammonia specifically?

NitrAte and Ammonia are nil. All the other fish seem fine.
Within the past 24 hrs I did put together a co2 cocktail of:

Sugar
Yeast
Baking Soda
Protein Drink Mix

I just did a 20% water change. He seems to be hanging out at the filter return.

If you have been newly adding CO2, this may be the problem. For two reasons. How much are you adding, and how much surface aggition do you have. You may be putting in too much CO2 and poisoning your fish. Also, with that low hardness and ph, you could be getting a ph swing at night, as the plants will start to use O2, and produce CO2, and thus causing an even greater influx of CO2. High levels of CO2 with low hardness, and neutral to low ph, can cause the ph to drastically swing one way, and back the next time the lights are on and the plants go back to producing O2. You should check your ph and your CO2 levels about 2 hours before the tank gets any light. And see if they are changed much.

Your first description sounds like either Ammonia, NitrAte, or CO2 poisoning. But, may be ph burn.

Acidrain thanks for all the good advice. My co2 seems minimal during the day, but I haven't check anything with the lights off. So I'll try that first thing in the morning. NH3,N02,N03 are all nil basically.
