Rbta & sps

Hello All, I previously posted about some trouble I was having with a RBTA. I was since able to take the unhealthy specimen a trade for a very healthy specimen that's doing very well. The RBTA has placed itself in the very middle of tank about 18" below an XR15 Pro at 70% intensity. It's doing eating well and hasn't moved in quite some time.

The tank is still fairly new - ~5 months - and consists mainly of SPS frags and small colonies. I know most warn against this set up as the RBTA will eventually move and sting the SPS or the SPS will grow and eventually get stung.

However, I see many pics of SPS tanks with a RBTA or other nem and tentacles are obviously touching SPS and everything looks great.

Am I missing something or is my set up possible long term to successfully keep the RBTA along with growing SPS colonies?????
