I'm not really sure yet what would be going into the larger tank... we do have a six line wrasse and a couple of clowns which might make the move... but it will be a while... maybe a copper banded butterfly?... not sure how well they would get along with the hippo and the others...shavo":2d7163o6 said:I would think you would be OK with a Hippo tang in a 135 or a 180, also you would probably be able to do a NASO or a Unicorn in a 180.
I have a small vlemengi (don't know how to spell it) in a 125 he has almost doubled in size in 6 months and they say they get really big. I may have to upgrade as well to keep him. Another tang that gets big is an orange shoulder. You just have to watch you don't get tangs with the same body style unless you ad them at the same time and you still may have issues then.
other than the hippo tang what are you looking for?
