Brooklynella ?

[deangelr]

I tried the disease forum and got no responses, so I thought I would give it a shot here since its so common on clownfish..


Is this brooklynella?

You tell us. I never look at them under the microscope so this is new to me. If your clowns got Brooks, and this is what you see, and if you look at healthy fish and don't see this then you got it right.

Exactly. No response in the Fish Disease Forum because few if any of us use microscopes.

If you wet mount the slide, you can see the Brook motoring around. With that cross section, not sure what it is. Scan around the slide a bit, match what you see with the a photo from Chucks Addiction.

Your microscope looks better than mine. I found Brook, but couldn't tell the difference between that and Uronema. Look for the notch.

These are larval fish.. Very small.. So there were no visible symptoms other than death.. The fish are too small to photo. Looking at them under a scope after they died this is what I saw.

Looks like it is brook. Thanks!

This means it's in our main system, as we use that water for the water changes in out larval grow out tanks.. I surprised that fish can live so healthy and you would never know they had it..

Steve, Have I offended you in some way? Your comments always seem unfriendly to me.. I apologize for any offenses..

 

[Allmost]

what kind of microscope do you use ?

No offense taken. I tend to be fact oriented; in point of fact few here do microscopic analysis so people who do not do this will tend not to respond. We all tend to devote whatever time we have to questions that we know something about.

A Zeiss..

Lol yeah, far better optics than what I have. Glad you got the ID. If the main tank is contaminated you will see fish dying off in under a month. I broke mine down and left it fallow for close to 6 weeks and treated all the fish.

 

[deangelr]

But thats what I don't quite get.. It has to be contaminated, but all fish are healthy fat and happy.. I can't figure it out!!

There was an outbreak a couple years ago that we eradicated in another system, but never treated this one..

 

[DasCamel]

Patient zero in my tank was a fat happy female clown. The other fish didn't exhibit anything until I pulled them out into a cramped QT. Such a PITA to catch and treat everyone.

Most likely if it present in the DT, you'll know soon enough. I QT even inverts now.

 

[deangelr]

It is a large breeding system.. It wouldn't be terribly difficult to treat, but I am hesitant to do anything when all the clowns seem healthy.. I even took several out and put them under the scope too look and couldn't find anything.. I don't want to be over zealous and just start stressing everything out, but also know that there has to be some parasites in the system.

That's tough. Keep an eye on the edges of fins, maybe try retesting in a few weeks. If you go 4-6 weeks w/o issues should be clear. The guys in the fish disease section think Brook doesn't linger w/o killing some fish or some signs.

I agree.
