Hi,

Firstly, before the shoulda woulda coulda crowd chip in… going forward I have invested in a quarantine tank now to never be bitten again on this level.

IME, buying from this LFS over the last few years I never had any outbreak and was lulled into a false sense of security.


Two of the three of my Anthias died suddenly, in retrospect they had been hanging with the peppermint shrimp a lot the night before, they looked healthy enough and CUC didn’t leave enough for me to inspect postmortem.

Dosed MinnFinn for the whole tank assuming that it was broad spectrum enough. Realised it wasn’t gonna treat internal and ordered some prantiquantel for internal parasites.

Now nearly the whole tank inhabitants are covered in ich or velvet or both?

Some hiding and some swimming directly into the powerheads flow, which is what makes me think velvet.
My Bella Valencia Goby is also clearly suffering an additional bacterial/fungus as a secondary issue, fins are tattered and splotchy body.

Because it’s the display tank I am trying to treat I am kinda forced into using MinnFinn, it’s had three of the 5 treatments and the fish look a little better.
Only one that would stay still was the clown, and he besides the Goby looks the worst affected.

Does anybody else’s experience with MinnFinn correlate with mine?
Is it normal for the fish to be cured but still look rough and behave oddly?
or should the resulting healing look more conclusive than this?

My next step after a full and very expensive 5 doses of MinnFinn, is to use a copper based medication, but to do that I will have to remove the corals (or frags of corals) into a quarantine tank and copper the display.
Or is Minnfinn useless in this instance and just go straight to copper.

I can’t put my fish in a 50 litre tank for weeks.
Don’t have room for bigger quarantine facilities, live in a tiny UK home.

Can you post a clear video taken under white light? I need to see the fish breathing rate in order to rule out velvet (Amyloodinium).

Minn Finn is just two peroxides - regular H2O2 and a peroxide salt. There are published doses for these compounds in treating some fish diseases. Trouble is, they don't give any sort of concentration, so dosing it is completely left up to their discretion, and hopefully they got it right.

I'd like to try and rule out flukes here. the video will help, but so will a timeline from when you first noted problems, when the fish loss happened, until today.

Here is a video.



Hope that works…

31st August Anthias hanging with peppermint for ages, no one else with outward symptoms.
1st sept anthias dead, dose Minnfinn. 30 percent water change.
2nd september fish with white spots/splodges
3rd second dosage of minnfinn, prantiquantel dosed.
4th rest and observe.
Fish seem stable but not better either. Goby for the few moments it appears from its cave looks worst, clown second.

The clown is breathing a bit fast. The moorish in the background is feeding well though, breathing just a bit fast. Does the tank have good aeration (not just circulation)?
Did you dose prazi 2x, or just once?

Velvet is really serious, but it usually causes rapid, massive fish loss. Flukes cause rapid breathing, but the losses from that are spread out for days/weeks.

This is the only thing I have found to do what you are suggesting. Many people believe in this method https://humble.fish/community/threads/peroxide-h2o2-dosing-for-parasites-in-reef-tank.725/

Doesn't this clear that specific dosing issue of "how much" question up? https://humble.fish/community/threads/peroxide-h2o2-dosing-for-parasites-in-reef-tank.725/

I would not recommend dosing copper in your display even if you remove frags. It will kill your inverts and will probabely later on leach from your rocks and kill your frags at a later stage.

Prazi has been dosed once, the next dosage is due ten days after to get the lifecycle completed… at least that was the instructions.

Currently the Goby is looking on deaths door, doubtful if she will make it, yet the clownfish has perked up a little.

If it is flukes kinda makes sense the sand sifter has been hit hardest.

Moorish is swimming around the tank more which I am hoping is a good sign.

Regarding copper, it’s my understanding that carbon or cuprisorb will remove the copper and make it safe? Is this not the case in practice?

I was planning on taking the hit on coral growth save some frags remove the inverts as they are easier to relocate space wise, and reset once the copper had reduced to safe levels…

But - we still don't know the actual concentration of peroxides in the Minn Finn product. Also, the few scientific references for using peroxides against fish parasites are based on moving the fish to a sterile tank after the dose. Peroxides do not control the hardier forms (life stages) of some parasites (fluke eggs, or ich or velvet tomonts).

Right, well, MinnFinn doesn’t work, or at least it doesn’t work by the time symptoms are showing.
3 doses 1 week and the death count is:

Goby
Bangaii Cardinal
3 Anthias
A cleaner shrimp
Lawnmower Blenny

And all the rest are showing signs

Going to try a fresh water dip to buy time.

I’m so ticked off at myself!
