A dying question?

This line struck me.. so your tank in theory could have been less than 2 months old? That's a pretty new tank. Did you start it up from scratch? If so, that is a VERY new tank. New tanks like that can be unstable and even after the cycle has completed need a little while longer to get its groove/stabilize/balance out etc..

In the first two months anything from adding too much fish to doing too much water change can throw the tanks balance off. You really do have to be careful in the first few months.

Did you set up your bathtub with brand new fresh saltwater ? They could have been stressed over a chemical imbalance due to the water change AND rock movement (potentially releasing chemicals), and then throwing them into a tub of newly mixed saltwater did them in. Anyway, that would be my theory.

Sorry to hear of your loss.
