Yesterday I get my analyze from
@AquaBiomics and it was interesting in many ways. As I suspect - it was not inline with typical tanks in some ways - but maybe not in the way I had expected. Start with the nitrification part. In this case it was normal - it is a functional tank that have been running for 5 years. Interesting was that my ammonium oxidizing organisms seems to be archaea's - not bacteria.
I know that it should show up some Cyanobacteria but I expected them to be in the group Oscillatoriaceae - but not. They was from the group Xenococcaceae - another benthic group. It could explain that my normal tricks with nitrate have not work very well in this case - nitrate level normally around 5 but during this sample - it was over 30 mg/L.
Now to the more unexpected result - the diversity (compared with other tanks) was not as high as I had expected
The balance was total unexpected - it shows up that my microbiome was closer to monoculture than to polyculture - att least on the group level.
There is one group that dominate - the Oceanospirillaceae. In this group both aerobic and anaerobic bacteria exist. I have a DSB with active reverse flow and rather high denitrification rate and at the moment the sample was taken - denitrification seems to be very high (other observations - NO3 was going down from over 30 to below 10 soon after .the sample was taken)
It also show up that I had a rather high presence of a fish patogen - vibrio fortis. However - I have had no visible signs of any disease in my aquarium. There was two individuals that disappear during this time - but they did not show up any disease problems - on the contrary - I notice a eye inflammation in two of my threadfin cardinals but - it disappear by itself after o couple of days.
The eDNA rapport coming with shows no known parasites ( note it is a no QT display) and report that I have aiptasia in the system. That I know because it is a colony in one of mu backgrounds modules there my aiptasia fighters do not can reach. It is also a place for a huge colony of sun coral so the module is feeded every day
It report no asterina but that´s not really the truth - i have a lot of them - or at least a small algae eating sea star. But it is doing i good job with my windows - nema problema. The eDNA also show a high prescience of sponges.
The picture only show the identified Eukaryotic not the non identified. It would have been good to know how many percent that could be identified because ther is a lot I know I have but not identified here,
Interesting results and worth the money for the moment. Maybe I´ll take a new test in a year or so,
Sincerely Lasse
