Subject line says it all. On Friday, noticed the tail fin on my Yellow Clown Goby looked a little ragged. Still ate fine and acted normal. Looked about the same on Saturday.
But yesterday (Sunday), I noticed it really flashing against rocks and my platygyra (it's normal "home"). Looking at it closer (hard to do with how small he is) his coloration is still great, but his skin appears "blotchy". Excess mucous, perhaps? I've seen ich, and it's not that. Doesn't seem "dusty" like Marine Velvet is described, but I've never seen velvet. Plus his respiration doesn't seem fast.
I was able to net him last night (phew!) and moved him into a QT. None of the other fish in the main show any symptoms and are acting normal. Water parameters in the main are great (1.024+ salinity, 8.2+ pH, 0/0/0.5 ammonia/nitrites/nitrates, 8 dkH/390 Ca, 77.5-78.5 degrees, 0 po4) and all fish, including the infected goby, are still eating normal.
Does this sound familiar with anyone? Basically flashing, blotchy skin, and ragged tail. I don't want to start treating for something until I have a better guess at what it is. (I've got cupramine and marycyn both onhand.) If it's Marine Velvet, then my other fish should show signs and the goby should be dead by tonight, right?
At this point I'm thinking some bacterial infection, and will adopt a "wait and see" position since I've got him isolated in the QT now. But I'm open for other ideas.
Oh... all fish have gone through quarantine for at least 4 weeks, and the goby was the last added to the tank, about 2 months ago (so I've had him 3 months). About 2 weeks ago I added a rock with mushrooms on it - no QT, but did a fairly long drip acclimation that diluted the store water by quite a bit. I then shook off as much water from the rock as I could.
