nah , large clowns dont cost that much, people are always looking to get rid a of larger ones as they tend to be too aggresive for the community tank. There is a 5" maroon @ my local LFS it is only going for like $35. I still wouldnt guarantee it's success though. I thought a 4.5" maroon clown and a 6" purple tang could fend off a small miniatus. one of my lower points in fishkeeping.
