First, congratulations on your CCB eating. Mine devours black worms but still will not eat anything else except pods.
Thanks! He now eats Artemia and Mysis with gusto [emoji4]!
1st. Your CCB's shaking MAY be a sign of excitement. I have heard this described before by other owners. My guy does this when I approach the tank, especially if I am holding a baster with black worms. I have watched him for hours and he normally does not do this at other times. I have never seen him rubbing his nose/mouth on any surface. I have seen him strike at pods or black worms lodged in tight places. Could this be what your are seeing?
No, this is not it. It is a bare bones tank so I have no pods in there. He basically scrapes his cheeks against the edge of the PVC pipes. As there are no white spots on either fish I am inclined to this being flukes. The head shaking however, as you mention, could be a sign of excitement.
2nd I use Paraguard for one hour dips at the end of my acclimation process. It is listed as a treatment for ick, velvet, other external parasites and treating external infections. It is a very broad spectrum tool but it is not the first choice for many on these issues. Its main active ingredient is Malachite Green. I have used this for years and have seen it kill ick and cure velvet. It does this slowly therefor a very sick fish will not be able to survive a severe infestation. That's why copper is better in those cases. Years ago I had my pharmacist compound cooper formulations. Seachem's Cupramine is a great leap forward but its still copper and copper is a poison. I believe, if your fish have shown absolutely no signs or symptoms of ich, your Paraguard at proper therapeutic concentrations will be plenty for your two fish.
Spoke with Seachem and Paraguard will not do anything for flukes. And I also had an experience when treating my fish where after 2 weeks of treating with Paraguard all of a sudden a yellow eye Kole tang that seemed fine through those 2 weeks died in one day from what I believe was Velvet. I switched to cupramine and managed to save the other fish that were in the hospital tank at the time, but kind of left me the idea that Paraguard is perhaps not ideal for Ich or Velvet.
3rd I am not familiar with Tremazol. But is sounds harsh. Prazi is fairly gentle and good for INTERNAL parasites, flukes. It does little for ich. If I have to treat a severe fluke infestation, I use RODI water buffered to 8.0+ pH and temperature matched, dipping for 10 minutes or until the fish shows extreme discomfort. I follow with treatment of Paraguard plus Prazro in a hospital tank. That works. Metro can also be used but it is hard on fish.
Lastly and of the school that does not treat in my QT unless I have observed a disease process. Good luck and let us know how everything works out.
