Start with DRY ROCK they said.. you WONT get nasty hitchhikers!

[lil sumpin]

Hello reef2reefers. Started up my first reef tank over the summer. It’s doing alright, yet to see a lotta growth but I am seeing a lot of things I’m unable to accurately ID. So I ask for your assistance…


A. These things came on a toadstool rock.
(Aiptasia?)

B. I see these things in the water colum sometimes swimming around… but mostly they’re on the glass. They kinda look like.. flowers..? Weeds?



C. From within a tiny crevice there seem to be some antenna looking things that sweep around. They’re kinda banded in pattern…


What the heck is goin on

Top looks like colonial hydroids. Middle also a hydroid. Bottom is a mini brittle star possibly

 

[ISpeakForTheSeas]

A - either "Aiptasia" or colonial hydroids.

B - these are medusa stage hydroids - unless they're a photosynthetic species or you have enough pods for them to feed on in the tank, they should go away after a while.

C - probably brittle/serpent starfish arms (should be harmless/beneficial).

Anything wet can bring in hitchhikers - these are probably coming in on frag plugs, CUC, etc.
