sp. A bright yellow

sp. B Aptasia maybe?

sp. C Unknown zoo-ish thing, prominant bright green on smaller polyps

forgive my lack of knowledge, im brand spankin new to all this

I didn't know where to post this snail, is he safe for my tank?

 

[FateX8]

first one looks like yellow polyps (Parazoanthus gracilis)
second one not really sure what it is, how big is that polyp?
third looks like a protopalythoa
and the snail looks like a cerith

 

[AlexStinson]

2nd one is 5mm or so across(not including tentacles), looks alot like pics ive seen of aptasia, reddish brown with a slightly lighter face

 

[FateX8]

i just dont know but something about it doesnt feel like an aiptasia
it looks like it has 12 tentacles which is making me think some kind of hexacoralia and aiptasias tend to have a LOT of tentacles, but then you said its only 5mm so maybe it has fewer tentacles because of age
do you kno what the base looks like? is there a skeleton underneath it?

 

[AlexStinson]

the base just gets larger towards the base, much like the yellow polyps do, and it will dissappear into a tiny ball when it is overly disturbed
