Re: Brooklynella Hippo Tang
I am very sorry to hear about your hippo tang possibly developing Brooklynella. Brooklynella is a very insidious parasite that must be treated immediately, as it can potentially be lethal within days. If indeed you are dealing with Brooklynella, the best medication that we can offer is Paraguard. However, Paraguard is unfortunately not considered 100% reef and invertebrate safe. If you do not have the option of quarantining the affected fish, then you really only have the option of treating with Metronidazole via a medicated food mix.
So, the best course of action, if possible, is to treat the hippo tang with Paraguard for about 3 weeks in a quarantine tank. This will give the fish the best possible outcome when faced with a potential Brooklynella infestation.
If you do not have the option of setting up a QT tank, then the only other option that we could offer is feeding Metronidazole. When utilizing Metro in a medicated food mix, it is not available in the water column and therefore your corals and invertebrates will have minimal exposure to the medication.
To feed Metronidazole, use 1 scoop Metro with 1 scoop Focus (a binding agent) added to the food once daily. You can also add some GarlicGuard to entice the fish to eat the medicated food more readily. GarlicGuard will also help to boost the immune system of the fish, helping to prevent possible secondary bacterial or fungal infections.

Best of luck to you, and we sincerely hope that your tang will recover quickly. Have a nice day.
