Something keep killing my fish

[Staisman]

I think I just lost my very healthy copperband. Last night he was fine eating with everyone and today I see him stuck to overflow with red spots on his body. Last year same happened to my clown fish. I was watching him swimming and next second I see him going crazy and die in couple hours with same red spots on his body.

I suspect my Foxface or Purple tang. Can those two be the killer fish ?

Unlikely - that looks more like a bacterial infection to me.

If the butterfly is still alive, you can try a combination of Furan-2, Kanaplex and Metroplex in a quarantine tank. Some of the gram-negative bacterial infections can kill a fish quickly - but they're not generally contagious.

I have right now Pimafix and Triple Sulfa. Fish in very bad condition but still alive. I put Pimafix already can I add Triple Sulfa too or it will be too much ?

 

[Staisman]

If it's bacterial could a water change be a trigger ? I did water change yesterday and He was fine all day yesterday and before I went to bad.

 

[Maritimer]

Water changes _shouldn't_ be a trigger ... but could add that little tiny bit of stress at precisely the wrong moment.

I wouldn't expect the PimaFix to do much of anything - use the tri-sulfa, but use it in a quarantine tank, not in your display.

Yea it's dead, was way too fast death for bacterial.

Red spots, maybe some kind of hemorrhage...which can be caused by sudden salinity changes. I had the same symptoms on my grandmas tank way back and found out her salinity was like 1.033 and she was acclimating from 1.018. Red spots and all.

I've also seen it with suspected cyanide caught fish, with that I noticed raised scales which i thought was indicative of kidney failure from the cyanide.

There was no salinity swing, fish were fine the night before and 7 am in the morning it was barely alive. The fish was in my tank for 3 month.

 

[Maritimer]

There are some gram-negative bacteria that can kill as fast or faster than velvet.

I'm sorry for your loss - copperbands are a favorite of mine, and this one looks to have been a very beautiful fish.

Very weird... I wonder where the bruising came from. Was it being bullied at all?

That’s the same thing I’ve seen in a couple of fish when I qt. They died very quickly. I believe it to be bacteria.

Sorry about your loss. If you have a microscope you could take samples and check. than you’ll know for sure.

 

[sfin52]

I don’t think it was another fish

Those red liaisons look like an aggressive bacterial infection

I had a fish in QT by itself and it died over night. The next day I found it with the same red liaisons which others on here diagnosed it to be bacterial
