Mysterious Fish deaths

[Kruss7]

In my 220g display tank I had 3 springeri damsels, a few weeks ago I checked on the tank in the middle of the night and found one dead stuck to my mp60. Thought possible fighting that I wasn’t seeing (had one with an eye injury previously that healed and haven’t seen any aggression since).

I moved on and this morning I come to find another dead, stuck to the exact same spot on my MP60 again. (They have guards on them). Both of these fish were swimming around hours before and eating. The bodies showed no signs of disease.

Not really sure what to think at this point, every fish in the tank has been fully qted with copper, metro, formalin baths.

Is there anything a that spingeri are susepctible to? Uronema? But I would likely see the spots and they would hide and stop eating before they die?

If they were fighting I figure it wouldn’t just be an instant death?

I would send off an AquaBiomics pathogen/parasite test. It won’t definitively say “this pathogen killed your fish” but it will give you some ideas of what (if anything) is in your tank that *could have been* responsible.

While they can get uronema, I suspect they were at point weak and/or the MP60 which is a powerful pump was too strong/turbulent for them. They cannot resist the power of flow and intake from a pump this strong. Other signs of issues would be elevated breathing, unusual swim pattern and hanging in area of less flow
Not saying pump was cause but may have been contributor

Not sure if I can get AquaBiomics tests in Canada but I’m 100% looking into it!

I’m going to keep an eye on the remaining one, was just really unexpected. They were always out swimming in the open and the pump they get stuck is a single one on the end of my peninsula, the other side has 2 mp60 and 4 mp40 and the 2 returns…

I agree could be a problem but don’t really have a solution my sps is important
