A couple of days ago I noticed one of my male guppies was lying in the corner of the tank gasping for air. His gills were red and fanned out, and he wasn’t able to swim properly, he just floated wherever the filter current took him. The neons were pecking at his eyes so I moved him into a net. An hour later he passed away. I should’ve took a photo of him, but I didn’t really think to post online for help.
I have no idea what killed him. I had him for 2 months, so I don’t think it was a case of a bad batch. A few months before I also had a small guppy that died suddenly, he had a single white spot that I thought was ich, but it then fell off and he died. None of the other fish showed signs of ich.
He was the thinnest of the school, but had a normal appetite and behavior. I don’t think the other guppies bullied him much, aggression seemed to be spread out evenly.
But now I’m worried, if I don’t know what killed him, could the other fish also have said cause? Would they die suddenly too? All of my guppies are male. Two of the guppies are very well fed and large, they also have a bit of a belly. Two are average looking, and one is on the smaller, thinner side. I also have a nerite and 6 neon tetras, 4 of which have grown larger and 2 that are still small, but could be juvenile males.
Ammonia is between 0 and .25, the color is in between on the API liquid kit. No matter how much Safe start or live plants I add, it won’t go to 0. It’s a 20 gallon and not overstocked or overfed.
Nitrite: 0
Nitrate: 0
Phosphate: 0
PH: 7-7.2
GH: 8
KH: 0-2
30% water change with prime weekly.
Could there possibly be internal parasites affecting them? If so, what do I do about it to prevent any more deaths?
I don’t have photos of the dead one, but I took some of the remaining 5 and some of the tetras, I just fed the blue one, his belly isn’t usually that big, the two large ones have always been that big though:
