Impulse decision? Maybe. Thoughts?

Okay - so I've upgraded from a 5.5g to a 7g bow - I hav an AC500 on for a fuge and a PH301 for extra water movement. I recently lost my A. Hectori goby who was one of my little tank stars, loved that guy - and I DID assume my pompom crab was lost - but no, he's still there - saw a quick flash of him today

Annnnyway - Fast forward to today, I was heming and hawing in regards to another fish - the last fish, to have in this tank, as my Blenny and Hectori have been in there since almost day 1.

I went to OA today to see what they had, and there was the most STUNNING ORA Neon Dottyback. The two had been there for months, in communcal tanks - so far, no problems. As he was the last fish, I didn't figure there'd be issues with my blenny, and so far so good - they're doing smashing. One thing I didn't think of/take into consideration was my sexy shrimp - I've got 2 that have been in this tank since the start.

He hasn't even so much as looked at them, nor shown any aggression towards anything else in the tank, he's claimed a part all to his own, and it all seems good - any signs I should keep an eye out for, suggestions?

Thanks!
