Which corals are these? Are they too close?

[taki123]

Hi guys,
Can someone help me identify these two corals next to one another on the rock?

also are they too close to each other? Or will they live together peacefully?

Palythoa and acan. They should be ok, but the palythoas will most likely spread faster than the acan - so allow for that.

 

[tcarstens4]

One is a type of zoa for sure, the other kind of looks like a Platygyra

 

[tcarstens4]

The walls of that coral look more stony than an acans walls

I could certainly be wrong (does look like an acan colony).

Pretty confident that the second one is a blasto colony. Zoas and blastos go fine together however the Zoa could outcompete the blasto for space.

Zoas and a blasto. You should be fine as zoas can take a good bit of abuse.
They will grow however so I recommend you give them their space

Zoas and some " brain" coral. the connected wandering coralites are the give away maybe platygyra or hydnophora

 

[fish farmer]

I'm thinking zoa's/palys and brain type coral, if some type of brain, they can send out sweepers.

If you gently blast the green coral with a turkey baster, do individual polyps close up in a branchy type skeleton or do they just tighten up on the base?

Not sure about when you turkey baster it but this is how it looks when it closes up at night.

 

[fish farmer]

Doesn't look like a brain from that pic...and a brain would have feeding tentacles out.

Not necessairly- we have a brain in our display that only puts out its sweepers sometimes and during the day or night

That’s a blasto I can swear on it

Looking at some blasto on Google and I think it is actually a blasto.

Can a blasto stay sitting next to that zoa? The blasto looks like it’s now stuck to that rock. Not sure if the zoas can be moved either.

do I risk moving it or just leave it and pray for the best?

 

[taki123]

So I think it’s this exact blasto I found on ebay

As mentioned earlier they should play nicely with each other however the zoa might compete the blasto for space, limiting its growth and spread.
I personally wouldn’t do anything about it.
here’s one of mine touching Zoas everything seems fine:

Blastomussa and zoanthus.
Palythoa have different tentacles. Acans look different and have circular corallites, and platygyras aren't as fleshy.

I usually don't put anything that close to each other, even if both are Zoa. One zoa can grow much faster than another one and just take over and it's usually the ugly ones that can just take over your tank. Leave at least 5-6 inches space between the corals.

Only problem is both are well stuck in their areas. Only one I could maybe move is the zoa but I don’t want to risk disrupting them and losing them. Lost enough coral already

 

[MrGisonni]

Yep a blastomussa
