So last night my mandarin just up and died from something I can't quite identify. Last weekend my butterfly died from what I thought was ich. I'm now left with two fish: a blenny and a goby.

The goby seems totally fine. The blenny has been, for the past few days, biting his tail and rubbing himself again soft stuff a little more than usual. Today, maybe because I'm paranoid, I have noticed him spending most of his time near the top of the tank (but the again he spends most of his time there usually) . They're both eating fine and neither are showing any signs of the typical "velvet" (then again, it's hard to tell on white and yellow fish).

What is your take on this? If it is velvet, should I move them to QT and medicate? Or should I observe them and see if they fight off infection on their own?
