Have had three fish(Sargassum Trigger, Midas Blenny, and Blueface Angel)in QT for the last week, all bought from the same LFS. On the morning of Nov 28 started to see symptoms which I wasnt certain of, but thought it could be Velvet. Knowing the quick kill time and rate of this disease I decided to take a punt and dose with Chloroquine phosphate there and then. Spent the last couple of days trawling the internet to see if I could get a definite ID for the disease, and stumbled onto this thread. Having spent five hour yesterday reading the entire thread I'm 90% certain my fish are suffering from flukes. Showing frayed fins, patches of what looks like bacterial infected patches on the skin, cloudy eyes, and the Blueface shaking its head from side to side. As I live in the UK the only product I can find with Praziquantel as its active ingredient is a product called Tremazol, made by Sera. This I already have and use as part of my QT procedure, not prophylactically only when I suspect flukes or intenal worms. Downside of Tremazol is that it is advised to use over a couple of weeks as a six hour bath then to either remove the fish or to do a 80% water change after six hours, because it causes a bacterial bloom, with the accompanying oxygen depletion(suspect it must also provide a carbon source in the recipe). I know have a problem if I use this, in that there is almost certainly fluke eggs in the QT which is 300l, so treatment has really to be carried out in the QT, a lot of salt water is going to be needed. As all three fish are feeding heartily and flukes doesnt appear to kill quickly, I decided last night to order Prazipro from the US and await its arrival before proceeding to medicate. Now the complication, awoke this morning to find flukes hanging off the tail and body of the Trigger, body of the Blenny, and the eye(looks like a mini contact lens)of the Angel. I have two questions really, has anyone ever found Chloroquine phos. effective in erradicating flukes, and secondly is it still worth my while in dosing the Prazipro? Apologise for the long post.
