Greetings.
I have a silvertip tetra that is struggling. It has been in a 10g quarantine tank for about two weeks since I bought it (in a batch of 20) from my LFS. Got the med trio for a week and now it is about another week later.
All the fish look good up to this one today. It's mostly on the bottom, struggling to swim (see video).
Checked water parameters, everything where it should be. (Amon, Nitrite, Clorine = 0, Nitrates = minimal, ph = 7.5ish, Temp is at 77-F).
Any advice on what happened to this individual and whether I need to worry about the rest is appreciated.
