If it is Marine Velvet... *Updated*

[ScubaSteve]

I don't actually know if it velvet or not. The butterfly had ich, I can say that for certain.. he may also have had velvet at the same time. The mandarin surprised me as I thught they were more immune to it than other. The mandarin had a white head... I don't know if this was velvet or if it was something else (like scratching on a rock).

Today the goby still seems fine but the blenny is quite bloated in his stomach. I don't know if it was because he over-ate yesterday (I've been feeding heavier to keep them strong), or if he's constipated for whatever reason, or if he's got something like dropsy (I think either of the former two). He's still out swimming, seems chipper but is still hanging out near the surface (which he usually does anyways).

I'm setting up a QT as I type this just in case, but I need some advice on what to do here...
