Need options for treatment, possible brook infected tank.

quick history. Brought a couple fish home from store that claims to treat and quarantine. A month later both died and 2 clowns that were happy and healthy before started looking ill. A week later both dead. My best guess based on symptoms and others opinions were a brook infection. 2 months later the remaining 2 fish in the tank seem happy and healthy (dottyback and mandarin).


What’s my course of action now? I would assume that the disease is probably still present in the display correct? Do I have to quarantine the two fish treat them and leave the display fishless for a certain period of time?

from Humblefish:

Fallow Periods - Below is the general consensus fallow periods for all diseases that require it. In most cases, it is 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.

• Black ich (turbellarian worms) - 4 weeks
• Brooklynella aka “Clownfish disease” or “Brook” - 6 weeks
• Flukes (monogenean worms) - 4 weeks
• Ich (Cryptocaryon irritans) - 76 days
• 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

During the fallow period, the fish must be quarantined and treated for whatever disease(s) are afflicting them (see links below). Successful treatment is imperative to avoid disease(s) from being reintroduced into the DT:

It's possible the disease was already present and the other fish are just managing it. As mentioned above a full fallow period and treating your existing fish are the only way to be sure it's gone for good.

This is what I figured. Without being 100% certain about what I’m treating for what should I do? Treat for the brook and go fallow for the correct time period, or are there other treatments I can do to cover other disease possibilities? From my previous research the mandarin is not compatible with copper based treatments.

Treating with CP would be your best course of action for the mandarin and other fish: https://www.reef2reef.com/threads/chloroquine-phosphate.192309/#post-2204093

Yes I’ve attempted to get a rx for this locally, no luck so far.

National Fish Pharmaceuticals sells it, Humble has had a batch tested and it was pretty good... upwards of 95% purity I believe. I would try that first, CP will cover brook, velvet, ich, AND uronema.

What did you end up doing with your Mandarin? I’m in a somewhat similar situation and worried QTing it would be a death sentence as mine doesn’t eat frozen or pellets.

I’d have to try to find notes or bookmarks. I did mainly observation in a second tank for a couple months while the main tank was fallow. I believe I did a couple weeks of CP at the end. It was easier though cause she eats frozen and pellet. It worked cause she’s still alive and the new fish never got sick after being quarantined prior.
