I had three yo yos in my 20-gallon tank along with a school of harlequin raspboras and two dwarf gouramis.
A couple of weeks ago this happened: everybody is happy and swimming then suddenly BOOM, one of the yo yos died with only a few hours of 'keeping to himself in the cave' first.
Then yesterday, exactly the same thing happened to the second yo yo loach. No symptoms, no real warning except for a short spell of inactivity.
The third loach seems happy so far and the other fish are just fine. Maybe he's a bully?
The tank parameters are fine and the dead fish showed absolutely no unusual signs.
