As a person who owned a pet store for many years not to mention the number of trade shows and conventions and seminars I attend, this was Just discussed in November and was determined through research that fallow periods for all diseases is determined by the
longest known time period that the encysted stage can survive on corals, inverts, rocks, substrate without a fish host to feed on. The fallow period starts when the last fish is removed from the tank.
These are now the Industry standards
- Black ich (turbellarian worms) - 4 weeks
- Brooklynella aka “Clownfish disease” or “Brook” - 6 weeks
- Flukes (monogenean worms) - 4 weeks
- Ich (Cryptocaryon irritans) - 6 weeks IF 27C/80.6F can be continuously maintained
- Uronema marinum - No fallow period, as it does not require a fish host to survive. It is an opportunistic parasite that strikes when a fish’s immune system has been compromised. Uronema mainly affects damsels (especially chromis) and clownfish.
- Velvet (Amyloodinium) - 6 weeks
