Tank specs:
10 gallon aquarium
Wisper 10i filter
Temp = 78F
Ammonia = 0, Nitrite = 0, Nitrate < 5ppm
PH = 7.4
Tank is stocked with two guppies, four cherry shrimp, 10 pond snails, 2 nerite snails, 1 assassin snail.
I am a newbie and have had this tank setup for 9 months. I have had a lot of fish die over the 9 months. I have gone through 5 guppies, and 9 pygmy cories (not all at the same time, I try to keep the bioload low).
I test the water regularly and have never had any ammonia or nitrite spikes. I do a 30% water change every 2 weeks and have never had nitrates go above 10ppm.
I have a blue guppy that has been a survivor since day one. He has thrived while his tank mates have gone on to greener pastures. When I got the guppy 9 months ago its tail was 100% blue. One month ago his tail started looking a bit ragged and started turning red. It has been like this for a month now and he seems healthy otherwise.
Is the red color a sign of disease? If so could that explain why I keep having fish die even though my water quality is good? If so, how do I treat it?
Here is a photo of the blue guppy its tankmate. The black and red guppy has not had any color changes, but its tail is also frayed.
