Also, post count means absolutely nothing... I’ve been in this hobby over 19 years and even active on local clubs. My current local club is slow so now I’m here on a national forum. So don’t judge by post count....

You're in the minority for thinking a 180 is large enough for a three foot long shark.

Also, post counts do matter when you know nothing about the poster. You have to assume they're inexperienced until proven otherwise. I've seen a lot of new people come through here, many of whom want sharks.
