Hi everyone. When feeding my fish this evening, I noticed that one of my Neon Tetras were floating at the surface and swimming irratically.
The spine seems very bent to one side, and his behaviour changes from trying to swim, and laying still. Besides that, the colours seem okay, and I don't see any bloating or cysts. Though he seems a bit on the thinner side.
My tank parameters were okay, I use the JBL Pro Scan app, and both nitrites and nitrates were in the green (though upper part) area. I immediately did a 50% water change and NO2 and NO3 are very low at the moment, but it has not helped as of yet.
The aquarium is a 60 liter Juwel Primo tank, with gravel and live plants. It also has a timer for the light, which is on for 10 hours a day. The filter is a biofilter that came with the aquarium.
The tank has 8 neon tetras in total, that were aquired over the course of august and september of last year. It also has a good amount of plants, but I have not added anything new since a couple of plants in november, and everything has been very stable in terms of parameters.
The fish are fed TetraMin flakes.
I regularly count my fish and for the past week I was missing one, so I checked the surface multiple times but could not see any dead or sick fish, so I figured I just couldn't see them all because of the amount of plants and hiding spots. But it might be that he had withdrawn from the group and hiding for some time.
Another thing to note is that when inspecting this fish it seems to be a bit smaller than the rest of the group. Also, the other fish seem completely fine and healthy (to my untrained eyes).
I've now quarantined him, and tried to give him a bit of food, but his condition does not seem to be improving, and he did not seem to be willing and/or able to eat anything. The bowl I'm quarantining him in now does not have a heater, so I can't keep him there overnight.
Any advice on what sort of illness this could be? Which steps should I take? He looks like he is in very poor condition, and has longer periods of not moving.
Here is a picture of my poor friend:
