Immunity/Resistance To Brook

[Coolcasino]

I had a mini tank wipeout. Lost 3 tangs, 2 clowns and some wrasses within 2 days. A fire fish a purple fire fish a six line wrasse and a tri color wrasse never showed symptoms. I would think they would be dead by now but its been 3 months and they have not died or have shown any symptoms. I did introduce a few test fish and they died within a week but the previous fish still didn't show any signs. I've tried to catch them so I can leave the tank fallow but I haven't had any luck. I thought brook was one of the more deadlier diseases. Can fish live with brook?

I've not heard of acquired immunity to Brooklynella, but it could happen. More likely, there are fish species that are simply not susceptible to it. I've not seen a comprehensive list, but clownfish are of course the "poster child" for this disease.

Thank you for the response!

The bad thing is I wont be able to add any fish until theses die as im sure these fish survivng brook means the tank isnt fallow and the brook will be living happily in the tank. Or maybe I will get lucky and I can trap them finally or they just commit suicide and jump out.

I think that if your existing fish are symptom free and you give any new fish a full quarantine, you will be able to add new fish after a period of time - 45 to 76 days depending on your risk tolerance. I didn’t think brooklynella has a resting stage like ich and velvet has.

Ohhh I didnt know that. I thought the tank would have to be fallow. I will give it a month and see if any new fish come down with brook.

I’m late to the party on this but curious how things worked out for you? I had a clownfish for several months that was great until I added another clown. The original started showing signs of brook after a few days of the new fish being added and died shortly after. The “new” clown, which I have to assume brought in the brook, looks great and I’m wondering if it could Have been an unaffected carrier. But, as you mentioned, I’m not sure about adding additional fish as long as that one is in the tank.

I waited a month after my last new fish died. Introduced a pair of clowns and they did not die. Added a week later a wrasse and he did not die. Added a fish a week and they are all well today. I'm pretty full now so I haven't added any new fish since maybe last October. Still have the fire fish, purple fire fish and the six line which is a total monster. I never found out who brought the disease in. The last fish I put in the tank was the six line and before that a wrasse. It had been a couple of months since the last fish had gone in so I was confused.

I hear six lines lose aggression in big tanks. How large is your tank?

125G. He has not lost nothing. He is roommates with 4 large tangs and a pair of blue throat triggers. He does not back down from the triggers and the tangs avoid him. Cant put any new wrasses as he hunts them down. The current wrasses are constantly looking over their backs.

If I were you, I'd remove the fish to a quarantine tank, treat them for brook, and leave the tank fallow for a bit to let the brook die off. No need to wait the years it'll take for the fish to die of old age.

I was considering a six line. I think ima go with a springer damsel for pest worms

Jay,

Apollogies for necroing an old thread, but it is highly relevant to my inquiry. I wanted to know if this is your opinion still in regard to brook?

I had a clown introduce brook due to poor QT by a vendor, I removed all my mollies, clowns, and some gobies and treated with metro for 14 days, observed for 14 more, then moved all to my frag tank. They are all living happily for near 2.5 months now in the frag tank.

I have a firefish who I can't catch for the life of me still in the brook infected tank that has shown zero signs of illness or stress the entire time. Given what we know about the brook life cycle would it be reasonable to introduce new quarantined fish back to this system?

Correction, it was actually been 5 months since the firefish was exposed to the brook and nearly 4 months that it has lived alone with zero signs of illness.

Since Brooklynella has a direct life cycle (no cyst stage) and since it has more specific host requirements than many fish diseases (clowns mainly) IMO, 4 months should be more than long enough for it to die out. Indeed, even if your original diagnosis wasn't correct, and there was some other parasite in play, it should still be long enough to have died out.

Thank you for your feedback, I did a fresh water dip on the clown in early stages and inspected for flukes and anything else I could think of, but signs looked very much like brook to me. Clown had classic early stage skin sloughing. Additionally, mollies started to fade and had slightly milky slime coat and started flashing - early signs on brook potentially. After metro mollies, and gobies are all fine.

I believe I am going to move forward with testing a few fish.

Thank you for taking the time to answer.

I think that mollies are another species that are prone to Brooklynella, but I'm not 100% on that because I don't normally keep mollies in marine tanks myself.

I have a wrasse and a coral croucher with immunity to velvet. I finally caught them, treated them and fallowed the tank and no more fish have died.

But can't a fish that is immune still carry and pass on the disease? A typhoid Mary fish.

Still have the same fish and have added a total of 10 others including a pair of clowns and 5 tangs. I did wait about 2 months without adding new fish but I never went fallow. I ended up catching the 6 line about 8 months after and he lives in my buddies tank. He was quarantined as I did tell him about my brook ordeal. Still alive aswell.
