Largest I hav is pushing 13". But I just couldn't get rid of due to how long it took to grow that large. If I were u, id look for some round 6", get on Massivore, and grow them out yourself. Think you'd get more satisfaction knowing u grew them out yourself. Otherwise finding anyone who has and will part with a 16" IT b hard to find, especially since IT's hard to push past the 15" mark in captivity in my experience. Best of luck either way u go!
