i feel awful i moved my goby to a larger tank as he was getting rather large and he died a week later.water chemistry is fine and virtually the same in both tanks i examined him and no apparent illness or injury he seemed to be doing fine and then out of the blue hes dead any thoughts?

Was there any rapid breathing or any other signs that something might be wrong or did he just suddenly flip over and die? Maybe you forgot to dechlorinate the water? (just a guess)

possibly lack of oxygen? how is the flow rate/surface agitation in your new bigger thank? whats the surface area?
