Led lighting/disease       1/21/20
Hey bob,
All of my fish have been thru copper, as well as two rounds of prazi pro.
There are about 30 altogether in my 180, from small wrasses and gobies you tangs.
I can’t help but notice when certain fish swim to my not powerful LED light up top (current marine, fish only type light) that these certain fish appear to have a white glitter in them. It’s only when they are under the light , at certain depths and angles.
The fish that show it are a masked swallowtail angel, an asfur angel and a blue ring angel.
Too numerous to count ( I feel it’s not ich) but almost like a paint overspray. Description resembles velvet, but nothing is dead and I’ve noticed this the past 4 days or so.
Again, 3 out of the 25 fish show it, no ones not eating, no lethargy, no swimming until power heads etc.
Could this just be the way the light is radiating off of them? Have you noticed this under leds?
<Could be a few things that are non-pathogenic. IF it were me, mine, considering all that is invested money and importance-wise; I'd be studying re sampling, looking under a scope re. B>
Thanks, bob


Re: Mycobacterial Infection       1/21/20
Bob,
<Eric>
Thought you might be interested. There is a company called Aquabiomics that does DNA testing on water samples and Biobeds.
<Have just read over their pdf>
I paid to get my tank tested and surprisingly there was no DNA evidence of M. Marinum in my tank.
<See this; in fact 0.0 incidence of all Fish pathogens... Bizarre>
Either I got the infection elsewhere (open wound/wet counter at LFS) or the bacteria was out competed. I attached my report if your interested in looking over.
<Surprised (very) at how much detail is available (presumably to all) in such a service. And, my understanding was that Mycobacteria were common, in fact ubiquitous in marine aquariums; perhaps not super numerary, but not 0.0 present. Bob Fenner>
