I don’t think so. The 40g hasn’t gotten any new animals or corals in a month, and the biocube fish were quarantined before adding them to the tank a week ago.That’s how I acclimate Reef Cleaners animals, I use fresh seawater and pull any DOAs that I see. I suggested that they change their info sheet to include this rinsing step, but they didn’t.
This is a bit of a mystery to me as there is no fish parasite that can be transferred on Inverts that will cause fish mortality in just 24 hours…just not possible. Having multiple tanks affected is also unexplainable in terms of coincidental issues.
If the reef cleaners animals are mostly o.k., and your existing inverts are also fine, that tends to rule out water quality issues and points to fish disease. Is there ANY chance hat a disease could have been introduced to all tanks 7 to 30 days before the fish loss?

The 75g also hasn’t gotten any new residents and doesn’t have any corals or other CUC.
