Crypto?

Ironically, my tang that died is the only live caught fish I have owned. All my fish that are captive bred are doing fine. I also read that all wild fish have the ich parasite but the immune system easily fights it off, but when these same fish are put in a confined space they can become stressed and makes it easier for the parasite to go to take over. Hopefully my other fish don't get it and I will just stay away from tangs. I've read they are among the more susceptible fish to ich, and I was pushing the limits putting the Kole Yellow Eye in my tank. Live Aquaria says 70 gallon minimum and I have a 90 gallon. But after you subtract the volume my sand, live rock, and overflow box take out, I'm probably at less than 70 gallons volume of water available for the fish to swim around in.

Thanks for the input guys.

That's actually super interesting, and that very well might be the case. I think its astounding how little we still know about some of the more common and deadly fish diseases.

They mean tank dimensions, not actual gallons. They know no one is going to place fish in a bare tank.

Now I am 100% sure it is velvet. The textbook symptoms didn't really match up with what I was observing on my Tang but my other fish that are getting it.... it is textbook velvet. Tiny white dots, and they are swimming into the powerhead. One of my bluehead fairy wrasse started showing the dots and then got better. I guess he built up a resistance. My Allen damsel has had it pretty damn bad for about 3-4 days now. He as a tough SOB for hanging on that long. His behavior is starting to improve but he still is showing the visible symptoms. Hopefully he builds a resistance and pulls through. Just noticed this morning one of my clownfish has the white spots. That's the only thing that really surprised me because I know clowns are extremely resistant due to their thick mucous coat. Hope he makes it.

I know you might think this is a cruel experiment to just wait and see which fish die and which pull through, but I think the outcome is information worth sharing. I don't have time to set up a hospital tank and do 20-50% water changes every day, and I'm not sure the GF would allow it even if I did.

First, you need to read up on velvet. Then, I would remove the fish to a second hospital tank. No, you don't need to do 50% daily water changes, that is insane. Indeed, you can use media from your display tank to start/continue the biofilter in the hospital tank. It won't matter if that media has the velvet parasite, because you are going to treat the hospital tank with copper or chloroquine phosphate and it will kill it, as well as cure the fish. Then, let display tank go fallow for 6 weeks (or longer if you want to get rid of any ich as well).

All you are really looking at is 6 weeks of a second tank holding your fish while they get treated. No crazy water changes. Surely the GF will be ok with that.

How do I know all this? Same exact thing with velvet happened to me. I had fish go from insanely healthy to belly up in under 24 hours. I used chloroquine phosphate, which I really recommend, esp. for velvet. Knocked it right off the fish, literally. But can't use in DT.
