Karin,
I keep coming back to this thread for updates and every time I do, I notice that I have stopped breathing and am holding my breath for you in anxiety over your fish... I know how you love them so!

*Exhale*... glad to hear there is a plan to put them in more water tonight. Sharing 10g sounds awfully stressful. We upgraded from 100g to 210g a couple of years ago and ended up losing only two fish in the process - a yellow tailed blue damsel and a blue/green chromis, both of which we had talked about finding another home for in the upgrade but had run out of time and energy! They were floating in a bag for temp acclimation and somehow that bag got sucked up and squished in such a way that there was no oxygen for them. So, floating too many bags in the tank at once to reintroduce our fish turned out to be our only real mistake (just did not notice that bag because there were so many floating at once).

Our fish were in one of those 100g livestock tubs like Alton's with only a couple of rocks and a couple of PVC pipes for hiding places, a heater and a powerhead going, and an egg crate thrown over the top for discouraging fish-jumping as well as cat curiosity. The fish did just fine in there for the estimated 36 hours transition. Our corals were all in 30g Rubbermaid tubs with no lighting and just a Koralia I think - might have been a heater too bc Mike is super-compulsive about temp stability.

It was a ton of work and a very long weekend... but it can be done! I honestly think Erik's mistake (Erik, chime in and let me know what you think) is that he got a tad over-confident after it had gone so smoothly and added too much new livestock too quickly after the upgrade, not giving the system enough of a chance to adjust, etc.

Anyway, please learn how to ask for help / accept offered help. ;) Look at all these amazingly generous offers. Next time you need to move a heavy tank, even just across the room, post it up here and you'll have a line of able-bodied men at your door in an hour (my husband probably being one of them!)
