Hydrogen peroxide bath, 175 ppm at 15 min.
I had to bail the flame wrasse, solor wrasse and xmas wrasse at 45 min as they were laying almost lifeless on the bottom, almost floating upside down.
Rest continued to 1 hr.

That might have been too many fish at one time (i.e. they started running out of oxygen).
@Humblefish Not true, in fact quite opposite.
When hydrogen peroxide is mixed in water, reaction is quick and it desintrigate into hydrogen and water, Yes water.
What is hydrogen perxoide? it has 2 hydrogen and 2 oxygen atoms H2O2 and it not as stable a water molicule H2O.
When its reacts with water it actually lets go of 1 oxygen atom producing more oxygen in water and remain atoms are left as H2O so water and oxygen is produced.

H2O2 → H2O + O2

So its actually other way around. Now why did the wrasses take the treatment so harshly? and not other fish.
Well here is the reason why.

Using an oxidizing agent can be harmful to the fish, especially the mucosal barriers of the gills, skin and gut. Using mucosal mapping tools, researchers have determined that harmful effects caused by hydrogen peroxide include damage to the delicate gill tissue and associated mucosal layers. Moreover the research reveals that the fish need at least 2 weeks to recover to a normal state - during this time, the animals might be more susceptible to aquatic pathogens as their primary immune defence (the mucosa) is compromised.

I can see the gills on the flame wrasse and outer layer is black.

so it does seem for whatever reason wrasses are a bit more difficult to h2o2 bath? i've done multiple at 150 ppm for 30 min, but never tried the higher dose or that length

i saw your video on youtube like an hour ago and was like uhh what is quarantined fish doing QTing that many fish in a 10 gallon tank lol

sorry about the wrasses. hopefully the biocellatus pulls through

how were they doing at 30 min?

i'm curious/nervous about the two wrasses i have. i *think* i ran into velvet and just coppered all fish in that tank, but i had two wrasses in there. all i did with them was 30 min 150 ppm h2o2 bath and then into their own tank where they've been for a couple months. no signs of anything on either one (cirrhilabrus and leopard) but the true test will be whenever petco wants to get in some black mollies. i've had such a rough go of using copper on wrasses, so if a h2o2 bath + wrasses natural heavy slime coat can rid them of anything external issues, that'd be so awesome.

Video is at 15 min into the bath. You can already see a lot of stress and heavy breathing and unease on all 3 wrasses.
I am finding out the same about wrasses. Copper and cp can be rough and now hydrogen peroxide bath as well.

yeah the ones i've done definitely aren't happy about the bath, but i never got the idea they were on the brink of death either. mostly sitting on the bottom pouting

pain in the wrasse indeed..

Here's another positive anecdotal report regarding H2O2: A friend of mine has been battling velvet with some fish, and BOTH chloroquine and copper have failed to eradicate it MULTIPLE TIMES. I know, scary stuff right?

So, we got to talking about H2O2 and I mentioned to my friend that @Dr.Reef has successfully ran fish through 175ppm for 45 minutes. Well, my friend likes to push the limits so he ran all of these fish thru 175ppm for 1 hour. The fish look great, no signs of velvet, etc. But now we wait & see if velvet returns (he transferred them all into a sterile tank following the bath).
Any update on if this? When I tried this symptoms reappeared after about a week. If it didn’t fully eradicate maybe he would have seen something by now.
