    Hey Guys,

    Can somebody please help me identify this colony that has just sprung up on my Live Rock?

    My camera cant get in close enough so I had to use my camcorder instead. Its a very short clip though :) thanks



    Its not aiptasia, i've had before and these are definately not them. When these retract, they retract into a tube rather than straight into the live rock like aiptasia does.

    Any ideas?

    Hmmm, moving them may be troublesome. They are attached to the largest piece of Live Rock I have at the base of my aquascape. What I can do is possibly direct more flow onto them.

    Just a side line question.

    Looking at the flow over these critters, is it too little? This is probably the flow rate in the entire tank. I have a Seio 320 and another 600l/h powerhead. The return pump is rated at 1200lph. I have wanted to get a Koralina but always worried it would be too strong?

    Anyways, back to the critters that cant be identified, or maybe they can. I'll see if I can get better photos :)

    They need "less" flow. From the video it looks as if they are getting pretty beat up.

    Hmmmm, more I can do, less will be hard since there is no pumps directed even remotely at them. I'll give it some thought, I may need to move some pumps around :)

    But then it really depends on what they are, if they are hydroids then I want them to be pretty beat up :D

    Once again, thanks anemone :)

    Very interesting ... I also noticed tons of these growing in my predator tank my mine are more whitish and have like clear bodies but they are very like delicate and feathery ... But these are not in high flow area .. actually they underneath my seio so dont get direct flow at all...

    I once had a colony of clove polyps (some kind of Clavulariidae) that looked a lot like these. They were even worse than aiptasia. I hope these aren't the same or similar. Because I recall resorting to smuthering them with high concentration NaOH to no avail... ::sigh::
