Hi, in one of my 10 gallon tanks I have 3 danios, 1 zebra and 2 blue longfin danios. The fish have been happy and healthy for a few weeks now (since I brought them home). Today when I noticed one of the blue longfin danios is swimming slanted to the right like this \ when just this morning it was fine. What's odd is the fish will not swim to its left and will often spiral downward almost out of control like a plane that's going down. I looked at the fish very closely, both eyes are in tact and physically I don't notice anything wrong except the left side seems a little limp (the fin still moves on the left side but the right one seems to be more active).
Is this a disease or an injury?
Water paremters: ammonia 0, nitrites 0, nitrate 20, ph 7 (where it always is), temp 79 and there's 1 and a half teaspoons of salt in there.
I did a 40% water change and decided since it might be an injury I'd treat with 1 teaspoon of melafix for now (that stuff won't do any harm anyway).
Do you guys have any idea what's wrong with my fishy?
Thanks in advance
