ID on 4 LPS I have.

[MeanGreenStompa]

Coral 1: always shruken, looks permanently unhappy.

Coral 2: shown steady growth, about double when i got it last dec.

Coral 3: I think this is Acan echinata, again doubled in size, never seen sweepers from it, but it stripped a chunk off a nearby cyphastrea.

Coral 4: often has it's tentacles out early in the morning (as shown). Slow steady growth.

I would greatly appreciate IDs on these corals.
I have 3 flame angels in that tank, any Lordhowensis I've put in there got reduced to nothing pretty fast. I also think that's whats happened to Coral 1, despite me never actually witnessing browsing by them. However I am now noticing that asterina with that streak of matching orange in it's flesh and wondering if that's what's happened instead?

IF coral 3 is an echinata, am I ok to put another echinata next to it or will they fight even amongst themselves?

2 looks like a brain coral. Maybe Platygyra. 4 looks like oolophyllia. A rare coral that is slowly becoming more common.

1. Micromussa
2. either Platygyra or Paragoniastrea russelli
3. Acanthastrea
4. would need to see it closed up to tell; likely Paragoniastrea australensis

4 looks like oolophyllia

valley width is too small to be Oulophyllia

IF coral 3 is an echinata, am I ok to put another echinata next to it or will they fight even amongst themselves?

Yes, it is okay to put echinatas next to each other

Thank you, here's a couple of pics of 4 without polyp extension.

I was wrong; it is an Oulophyllia
