I am not sure
I kept a very small (too small in my opinion for it to be viable) frag of a beautiful blood red A. hyacinth, and it had corallites that looked alot like a table form of A. mille. So I would say they looke similar, but mine came from a colny that was very tightly buched, and was very table like in shape, only the very edge had branch tips that were not connected to a table base.Your pic shows some longer branches.
Thats a nice peice though. You better slow down or your gonna run out of space b4 you can get the other tank together.
By the way it lasted about 1 month then started tissue recession, but the frag was a tiny 3/4 inch frag with a couple branches, and it came off a wild colony. It was a freeby, so I tried, but knew it was an uphill battle due to branch size. Thats one reason I like a 3 inch or more frag of anything. Gives the little sps a chance to make enough food to live and enough food to lay down a healthy base..
Where is the updated tank pics?????
