Time for an update as there has been an interesting change of events...
To cut a long story somewhat short, I inherited/rescued a tank full of fish from a local guy who was moving and had to get rid of his fish to break down his tank to sell. He insisted I take them for free, as he needed them gone right away. I ended up with a couple that I am not going to keep...a Lyretail Grouper. (about 12") and a Picasso Trigger (about 6-7"). Those are going to a LFS tomorrow. The fish I hope to keep are a 12" Engineer Goby, a Djardini Sailfin Tang and a regular Sailfin Tang (both about 7-8", thick and have been paired for almost two years), a Toby Puffer and a medium Porcupine Puffer. There was also a big brittle star.
Right now, the Grouper, Trigger, Brittlestar and Goby are in the 240g. As I said, the Grouper and Trigger are going to the LFS tomorrow. Cool fish, but won't work for my long term plans.
The Tangs and Toby are in my 45g that is a QT/Holding tank. I'm doing daily water changes and using Prime to help with Ammonia/nitrites. They seem to be doing okay...eating fine.
The Puffer (Simon as named by this guys daughters) is in a 30g in my son's room. Doing daily water changes there too. He's doing good as well. Huge personality.
Once I get the Grouper and Trigger out of the 240g tomorrow, I plan to move the Tangs and the Toby into the 240 and the Porc into the 45g for a while, in hopes of not overloading the bio filtration any more than necessary.
The kicker is going to be the Ich factor. I had the two Chromis in there and one appeared to have something at times. It came and went, so I'm still not 100% sure what it was. I pulled both out and was going to leave the tank fallow. I am considering hypo for the DT if it comes to that, but time will tell...
