Hello,
Have you researched any of the articles regarding hydrogen peroxide? It for certain kills ick and velvet and I have to find my sources on the others. For your size fish I would use a 40 breeder with the proper copper treatment.
Most quarantine protocols for marine fish include
a routine copper treatment, which is typically continu- ous for 21 to 30 days. This would be done at the 0.15 to 0.2 mg/L free copper ion concentration as previously described. This treatment should eliminate A. ocellatum from fish while in quarantine, but biopsies should still be used to ensure that fish are not harboring parasites. Poor efficacy, or treatment failure, when using copper-contain- ing compounds in marine systems is usually associated with inadequate monitoring of the free copper ion con- centration to be sure it does not fall below the required therapeutic level. This allows some parasites to evade treatment and can result in an outbreak several weeks after the copper treatment has been discontinued. Fresh- water dips may also be useful in eliminating dinospores and trophonts from fish.
As well prior to you placing them in your qt I would use a 40 breeder myself, maybe a 75 if I had larger tangs but prior it’s been noted that,
“Freshwater dips of 1 to 3 minutes cause A. ocellatum trophonts to detach from infected fish (Bower et al., 1987). It is unclear whether this is sufficient to actually kill them, however, and given the tolerance of trophonts and tomonts to environmental conditions, it may not be prudent to assume that this would happen. Noga and Levy (1995)”
As well as have reviewed a number of drugs that have been used in efforts to disinfect systems contaminated with A. ocellatum. Of these, benzalkonium chloride seems most promising for use as a routine dis- infectant in aquaculture or aquarium facilities, although the compound is not FDA-approved for use in fish. This chemical is in the group of disinfectants known as quater- nary ammonium compounds. (Noga and Levy 1995).
Again another strong source to help is level 2 uv and ozone. With that said I’m still learning about how mine will use the ozone and the severe precautions that come with it which also inlcudes not only killing my fish but myself as well. It should be known that these treatments only prevent a larger out break by killing the free swimmers. There still has been no development for tomant and trophant stages. I would also treat with an antibacterial during this. The fresh water dip will also help to elimanate flukes as well.
