I bought a BTA (which was sold to me as a LTA :/ ) and it would not stop moving around my tank at first. It eventually walked all over a patch of zoas. I noticed after this a pink slime-like substance at the roots of the zoas, and honestly thought they had been stung and were as good as dead. Since then that zoa colony has been growing great, and I've just ignored the pink substance. Today was the first day that I've seen small tentacle-like pieces coming off of this substance. Did my BTA spawn? See pics
