After what appeared to be a successful copper treatment (Cupramine, tested with Hanna) of 30 days, fish looked much better. No ich/velvet behavioural/visual symptoms so I removed all copper and I switched to 15ppt for treatment of suspected prazi-resistant flukes.
Fish began flashing again once the salinity was dropped and over the course of 7 days the flashing has become more frequent and some fish are displaying rapid breathing.
- Fish are still eating mostly, maybe a slight appetite suppression.
- Still no visual signs of ich/velvet.
- Lots of surface agitation (HOB filter, air stone, wave maker).
- pH kept between 7.7-8.0 during 15ppt.
- Ammonia levels 0.
- 50% WC every 4 days.
I'm thinking my next course of action has to be to raise the salinity back up and try an alternative treatment for flukes (Flubendazole).
Do you agree with this method and what should I do if flubendazole is unsuccessful? Could I be looking at some form of internal flagellate which needs medicated food to treat?
