What Are These Fish Dying from?

[dr.sinister]

First a multifasciatus angel I didn't even know was sick, then an Atlantic Blue Tang was hiding yesterday and not eating and then died today after treatment with formalin. Looked like laboured breathing. Tank param are all excellent as it is a coral tank with very few fish.

Why the heck would you treat the tang with formalyn? This is used for specific diseases like Brooklynella. A little more info is required from you. Were your fish sick at all or did you just treat because you felt like it?

Formalyn is extremely toxic and must be done EXACTLY as directed in a hospital tank and you MUST use an airstone to oxygenate the water as it depletes oxygen rather quickly.

Hopefully you didn't use formalyn in your "coral" tank, because if you did I would expect them all to be dead in a day or so.

You need to provide a little more background info if you want more help.

LOL!!! Of course I didn't use the formalin in the coral and I know how to treat with formalin and used the appropriate amounts and a few fish have had brook in different systems so I have used formalin with great success.
What I want to know is what would kill a fish in less than 48 hrs
that is not velvet or ich, leaves no marks on the body and that causes the fish to breath heavily and the gills are bright red?

Your attitude could be a little better but I guess that what happens when people think they know everything

Brook can kill very quickly a few hours to a few days when you see the signs. I know that some fish can have ich and not have the typical spots but it causes inflammation in the gills and they basically suffocate. Sorry about your fish. I am in the middle of an ich outbreak because my heaters died and I did not know right away.

Keep it polite.
The other thing that can kill quickly, particularly those two species, is oxygen deprivation: gills affected by ich or flukes; or oxygenation shortage, sometimes coupled with somewhat high water temperature.

ya I thought that it might be brook and thats why I treated with the formalin, however it seemed to kill the fish faster than the previous fish with brook, I thought maybe flukes but I don't know what to look for. Can you recommend a good article?

 

[lisafoster]

Sometimes just the stress of moving and aggressively treating with meds can be enough to stress the fish so much they die. I just let the fish stay in my DT and hope for the best. Many times once you see signs of velvet and brook it is to late anyways.

Only thing I know I'd get from Google: Wiki probably has a good article. But I've never personally encountered them.

The only treatment I have seen recommended in the case of flukes is PraziPro.

I would say, first of all, if you are consistently getting fish with problems, change your fish source. I have never in the last ten years gotten a fish with ich or parasites from my online source, one of our sponsors. Certainly toughen and lengthen your quarantine regime.

I'll be the first to admit that I don't know everything, but go back and read your first post. When someone asks "why are my fish dying?" and provides no other info except that they are using formalyn and the fish is breathing hard and there are corals in the tank, what are we supposed to think and say?

Good luck.

"Tank param are all excellent as it is a coral tank with very few fish. "

I'm a bit confused, if this isn't the tank you treating or housing the fish in how does this help?
