My Glowlight Danios keep dying
About three weeks ago I bought 10 glowlight danios. These are really pretty fish. They were all healthy and active. Eating well.
The last two days, I've lost three of them and I can't figure out why! I see them at the surface gasping for air. Swimming erratically. A few hours later they are dead. This has been happening one by one, not all at once.
I do dose CO2, but minimally with a drop checker. Once the first fish starting acting like that I turned off the CO2 just in case and increased surface agitation. He died shortly after. By now the drop checker was solid blue. I lost another one last night with the same symptoms. I checked water parameters and they were as normal......0 ammonia 0 nitrite very little Nitrate if any.
As I was prepping for my weekly 50% change, I noticed another one showing the same symptoms. By the time water change was completed he was still swimming separately from the school and gasping for air at the surface. He was dead an hour later.
My PH is a little on the high side. around 7,6-7.8 with CO2 and around 8 with it off. It's always high, but I don't feel high enough to worry about.
I have other fish. 4 dwarf honey gouramis and about a dozen Neon Tetras. Also a female Betta, 50 or so cherry shrimp and several nerite snails. I'm only having this issue with the tetras.
I can't figure out the problem. It has me worried!
Any Suggestions or ideas would be helpful.
