Goby dying? -video - need help

[azilko]

This seems to be the second fish in about a months period of time that this has happened to... The first died. I thought it was due to chemi-clean usage. This happened a few weeks ago though.

This fish was fine yesterday. The only thing I've done with the tank is pull out the filter box and wash the poly-filters and carbon bag, & put it all back.

The coral & all other fish (blenny & 2 clowns are all normal).

Here's a video of the goby. What you can see is all I can see. He is at the very back of the tank. I have no way to catch him unless I ripped the whole thing apart. Any thought on what I can check for or try?

How long has your tank been set up? Have you introduced anything new to the tank? How long have you had the goby? Did you quarantine it prior to introducing it to the DT?

The tank is 2-3 mos old now. The goby was the last fish added after the last fish died.

The goby just did its death swim (and acted EXACTLY like the last fish that died 2-3 weeks ago). I was able to net the gobe, and will take a bunch of pics to help figure out the issue.

If it were itch or velvet, would this happen this fast (being that the fish was eating yesterday)? Or could the fish have been "stung" by a bristle worm or bobbit worm (I fairly sure I have one of these)?

I don't have a QT setup (although I spent the last 2 hours reading about them, and will be setting one up).

The Blenny & 2 clowns are all that remain...

Here's an image of the fish... Any thoughts on the cause?

Don't think this was ich or velvet. What is your ammonia reading? I would say it looks like a bacterial infection but given the gills are red I'm leaning towards ammonia toxicity. Did you get both gobies from the same LFS?

All my fish have come from my LFS. I took my water in an hour ago, and ammonia (in addition to PH, Nitrate, Nitrite) were all good. It's odd as no other fish are displaying any issues.

I like that you're leaning towards something though that I can look into. My LFS had no idea what the cause was as the water reading are all good...

Anything else I can test for or should try?

 

[Newsmyrna80]

At this point there isn't anything to test. I would, on your next fish, use a QT.

 

[azilko]

Thanks for the input at any rate. I'll need to get one setup. What I don't know though, is if a QT would've helped as this fish was in the tank for 3+ weeks w/ no issues, then over 48 hours, showed symptoms and died (which is what the other fish did as well).

I'm really at a loss at this point.

If it was something that could have been identified and it could have been treated right away and also would not spread to the other fish.

looks like ammonia burn or some sort of chemical that burned its gills

Yep, ammonia was what I said but the LFS checked ammonia.
