How big are Tubs Blue Zoas supposed to be?

[georgec]

I’m pretty sure these a Tubs Blue zoa’s I got from
DBTC a year or two back but can’t seem to find the thread or anything in my PMs.

My question: these were small when I got them, but haven’t gotten any bigger (zoas on the bottom vs the others for reference). Are zoas usually this small? The frag has doubled in size (there’s another piece split elsewhere in my tank).


Thanks!

The ones I had were small compared to other zoas

Tubbs blue zoas are smaller than most zoas. The coral above it looks like it could be a paly which are larger in size than zoas.

Thanks. Just making sure there was something else going on. The ones above are normal sized zoas (closed up because I had just fed)
