Hi folks
In my planted freshwater aquarium, housing mostly tetra, one of my two biggest tetra (I suspect they are diamond tetra) has started looking weak, thinner, lethargic and has a weird grey discoloration. I cant tell if there are grey/white deposits on it or not.
I only noticed this today.
Ive included a video to show its state, as well as the state of the other of the two tetras who looks 100%, for comparison.
Anyone have any ideas about whats going on with this little dude?
