Since the last update...
My ARID reactor arrived. I started it up seeding (not kidding) about a table spoon of Chaetormorpha into it. Initially ran it for 8 hours of day but I recently up'd the run time to 12 hours a day. I cleaned the ARID today and I was disappointed. I expected tons of Chaeto but I barely had a tablespoon remaining. but I am not going to judge this too quickly since I did not follow the directions exactly.
The first fish I added back in January were three Yellow Tangs. It seemed like one of them might have flukes but after a few weeks, they were swimming around fat and happy so I added some ORA fish. At the end of March I lost 1 of the YT and I am pretty sure it was flukes. I continued monitoring things and the other two tangs went down hill and I have concluded they have flukes (they have what I think are classic symptoms: white margins around the gills, other blotchiness, loss of appetite, shaking their 'heads'). They have not been sick enough that I could catch them and at night they sleep inside rock structure so today I decided to treat the system with PraziPro. Almost immediately after the Prazi hit the DT, brittlestar legs appeared from in the rock and the Xenia and Clavularia closed up unhappy. After about 15 minutes, the Xenia started opening up like normal. I don't know if the stars are dead but the the legs disappeared from the rocks. In the meantime, the appetite of the tangs has seemed to improve. They have both been grazing on algae on the rock work and swimming more in the open so I am guessing the flukes are dropping off their gills, etc. Snails, Conchs and Chitons are unaffected. I have a couple of hermit crabs but I can't find them so I don't know if they are kicked it or ?
To dose the Prazi, I turned off the skimmer per the instructions but the instructions don't indicate if you are to leave the skimmer off for the whole treatment. Does anyone have any experience dosing their DT with Prazi? How long did you keep the skimmer off.
I have some video of the YT with the fluke symptoms as well as the the unhappy Xenia. I might post that later.
