RBTA's and Mags

I have 60 gallon would there be a problem?

Size shouldn't matter but area for the nems may. Some will physically attack each other. Mags usually spend their time high up on a perch getting light and flow and bta stay lower. Long as they find their happy places and don't wander you should be OK. I'd get the mag first let it settle then get bta.
