Every once and a while when my BTA is fully inflated and the current in my tank hits it just right a stray tentacle or 2 will brush my sun coral. The BTA retracts violently but the sun coral seems unaffected. Anyone have any opinions on whether or not the BTA is actually hurting the sun coral? I'm in the process or arranging a trade for a smaller BTA but I don't want it to hurt my sun coral in the meantime.
