moving tanks - combining fish?

We are remodeling our house, and will soon have to move the 75g and the 12g nanocube into a different room.

Currently the 75g only has a foxface and a single chromis (his friends have gradually died off over the past year). The nano has a yellow clown goby and a citron goby.

I have been thinking about taking down the nano, and putting all four fish in the 75g. Is this a good idea, bad idea, with the combination of fish I have?

I'm going to take this opportunity to do a completely different aquascape, and after the tank has been up and running again for awhile, I'd like to add a couple more fish.

What do you all think?

 

what i would do if i were you is move what aquascape you have now around. (make the foxface and the chromis less territorial). aclimate your goby's and you should be fine. also wont hurt to turn your lights off when you do this. I would also add stress coat to your water befor you add the goby's.

 

The gobies are weak at competing for food so you will need to take that into account if you do combine the tanks, hopefully the fuge will overcome this issue.

 

I really don't want to risk killing the gobies if I put them in the bigger tank. I've had them for over a year and they are doing great. Very active and amusing fish!
