Hi, I've had my tank for about 4ish months now. Everything was going fine until the begining of this week. I noticed I may have had some fin rot on my guppies to I went out to buy some medication.
The day after one guppy died. I did about a 15l water change. Today I have noticed all my fish are gasping for air and look red around the gills. I thought it may have been amonia poisoning but I testest and was at 0. I have attached a picture of a guppy on the bottom gasping for air.
Last week my tetras were doing fine but it now seems they are breathing heavily
I recently added 4 amano shrimp.
Ph 7.6 (normally higher)
Amonian 0
Nitrite 0
Nitrate 40+ (I can't really tell the difference between 40 and the next one up)
