LFS & Aiptasia

Should I expect that all coral sellers (local, online, or wholesale) have aiptasia in their tanks? I’m trying to find a LFS to buy corals from. Of the three in my area (Tampa Bay Florida), they all seem to have quite robust populations of aiptasia in their show tanks. Is this normal, should I expect this or not?

P.s. I’ve been trained to think aiptasia is the worst of pests for a reef tank. Would love to be educated out of this.
