Are these corals too close?

Yes, Looks like that acanthastrea already could sting the bejeezus out of that nice Acropora
Spatulata you have there if its tentacles were extended enough.

I don't know if that Acan has longer sweeper tentacles, if it does, that Acro will get stung, even still in a very short time they will be too close....I can't tell from the angle of the picture how far away the that frogspawn is from the other 2, but it can sweep a pretty decent size area, so I would monitor that for sure.

Corals are a lot like people. Sometimes they get along just fine. I have some that grow into each other and don't seem to have any issues. And other can't get along with anybody. I have some corals that anything gets even nearby will get stung and killed.

 

[Dkuhlmann]

I find that Acan's are happier in the sand. I would move that and you will be fine on the distance between corals. I use a rule of them when unlike corals are near each other to leave about 6" in between.

Remember that both are micro Colonies (frags) and have a much larger mature size

ya looks like they're too close. i would move the acan to a lower place or sandbed like suggested above.
