If you are sure what the fish had was velvet (Amyloodinium ocellatum
), copper was the best option as hypo will have no real affect of marine velvet. If at all possible, 6 week is better when dealing with parasites. I would push for 4 weeks as the bare minimum. It's not just the main tank you need to be concerned about. Once the fish have gone through the optimal treatment time you should allow an additional 10-14 days in the QT
after all meds are removed to be sure of no re-occurances.
Stress, environmental conditions and food types will definately have an effect on fish's health in general but Regals are what I would call the hypocondriacts of the marine hobby. If it's possible, they'll get it. Carbon as a cause of HLLE
is a new one on me. I highly doubt that one.
The copper could have definately been a contributor if using an ionic copper. If this ever happens again I would definately suggest you use a chelated form of copper or better stil, Seachems Cupramine
. If C. irritans
(ich), follow scuba_steve's
advice on the hyposalinity
. It is the absolute least stressful treatment when done properly and will not affect the biofilter in the least.
If possible I would suggest trying to post a pic of the tang. Being you where treating for a parasite problem it is quite possible the tang is suffering from a secondary infection brought on by the actions of the parasite. That will be much easier to heal than the HLLE
with simple antibiotics. If truely HLLE
, you will need to get water quality up to optimal ASAP
. Tangs in general do degrade quickly if so. Be sure you nix the meaty foods for the most part. Once in awhile is fine for the tang but it's diet should consist of vegetable matter high in spurlina algae. Nori is a great grazing food.
If it ends up being HLLE
, I would also suggest getting some Selcon or Zoecon to soak foods in for the tang. It's very high in major vitamins and [acronym="Highly Unsaturated Fatty Acid"]HUFA
[/acronym]'s which will help the healing process during and after water quality has been repaired. Beta Glucan
is also a great self helper if you can find it.
