I joined a group buy back in May and it was supposed to be 2 favias and 4 blastos, but one of the blastos is not a blasto. We can't figure out what it is. It's the one on the bottom left in the pic.

Any suggestions or ideas would be greatly appreciated.

acanthastrea lordhowensis.

Are the acanthastrea lordhowensis typically slow growers?

I agree with Acan, they can grow fairly rapidly if you feed them 2 to 3 times a week.
