Checking coral compatibility with seahorses

[JoJosReef]

A few corals I wanted to double check on:

Sold to me as a platygyra but may be a favia (??) (@thamnasteroid any idea?). Safe or not safe?

Caulastrea; seen on some lists as safe:

I do not know if this is an elephant ear or not. Never seen it attack fish, but my fish are larger or faster (wrasses), so maybe not possible for the shroom.

I have this other magic carpet-like shroom that is quite large:

And this is its feeding response when white worms drift into its little tentacles:

Same as above, I've never seen it do anything to fish, but I have fast fish. I also don't think this guy stings (white worms just kind of fall somewhere and wiggle), but I don't know.

Mint Potato Chip Pavona:

Green cyphastrea:

I understand that monti caps are generally OK, but how about branching psammacora? These two guys have kind of grown into each other:

This was purchased as a "scroll coral", which I understand is similar to or a type of Turbinaria, which I've seen on the compatibility list:

Cynarina... I've seen cynarinas, acanthos, scolys, lobos and trachys on both compatible and incompatible lists. Below also my trachy and lobo:

Lobo definitely has some tentacles on it and white worms stick to them easily.

NOTE: presumably the dendro is incompatible??

Every other non-softie in my tank has no chance of being compatible, I think. Love my RFAs, but I don't want to risk it despite their weak sauce tentacles.

Bumping.. I don't have any experience with these guys.

Thanks!

1. Paragoniastrea australensis (true Favia don't exist in the hobby; ex-Favia also have monocentric corallites)
2. Astraeosmilia curvata
3. Rhodactis; pseudo-tentacles don't look like elephant-ear (Amplexidiscus)
4. Actual elephant ear (or rhodosoma, I'm not sure)
5. Pavona cactus
6. Plesiastrea peroni, not Cyphastrea
7. technically not a cap; true capricornis don't have any coenosteal ornaments; Psammocora is contigua
8. Turbinaria sp.; cf reniformis
9. Cynarina lacrymalis
10. Trachyphyllia geoffroyi
11. Acanthastrea pachysepta, not Lobophyllia

Thanks! Was just asking about the "platygyra", but all the other are a nice bonus!

4. Actual elephant ear (or rhodosoma, I'm not sure)

This I find surprising. Are "magic carpet" shrooms also elephant ears? I was given this one as a replacement for a diaseris I ordered that did not survive in store and was told it is "magic carpet-like". This shroom seems to aggressively envelope food that lands on it, but I wouldn't have pegged it (yet) as a fish-killer. Do you know if this specimen would be dangerous to fish like a seahorse?

11. Acanthastrea pachysepta, not Lobophyllia

I guess this explains why my "lobo" was so aggressive toward a neighboring goniapora frag and murdered it with mesenterial filaments. This again makes me wonder if it would be a risk to seahorses.

Thanks again!

Magic carpets are rhodosoma, not elephant ears. Elephant ears are much larger, are usually grey in coloration, and have a distinct ring near edge of their polyp where their muscle is.

I was actually just watching a video of a person who owns sea horses in a mixed reef successfully so it's doable but I recall seahorses need colder water temperatures so I suppose you'll be running at the upper limits of the seahorses and lower limits of the corals, but I no nothing about sea horses so take that with a grain of salt.

Thank you! Is this the ring you are referring to on this picture of Rhodactis mussoides I pulled off of google images?

The images I've found of R. mussoides looked like they had more uniform papillae (or verrucae?), whereas mine is quite irregular. I read also that R. howessi is an elephant ear, and the pictures of their papillae look much more similar to mine, albeit most of them were "green fuzzy/hairy shrooms" and not the bronze-yellow coloration of mine, if that happens to be a defining feature.

In any case, now I'm a bit concerned about my shroom.

Yes, that is what I am talking about.
