I found this on a coral frag i got a few weeks ago.

Bubble algea....gets it outs. Kinda cute atm...but give it a bit to take over.

That small I'd pull the frag...toothbrush it in some tank water(edit out of the tank like a bowl) to get that stuff off...and do a coral dip before putting it back.

Also you can break off the plug bit of those frag plugs pretty easy so it will sit flat if you want :)

Take it out of your tank to remove it.

And just in case you're talking about the black blob....

Touch it. If it withdraws a little, it's a tunicate. If it does nothing, it's a sponge.

really? just in general? Cause my sponge moves a lot really ... need to go poke what I think are tunicates

In this video you can see me touching my tunicates. If yours pulls back like that, it's a tunicate. Sorry about the quality, I've hidden the originally from myself somewhere.

Im pretty sure moves vs not moves isnt the difference though.

If I had some video my red something no idea what sponge hitchhicker...will go from an inch to a 1/4 inch thick or 3 inches tall to 1 inch tall it can move. And it's so not a tunicate...tunicates only have one opening. Is my understanding.

Perhaps it's an encrusting sponge...vs standing?

To the original Q.....black thing isnt a problem more geeks showing cards....but get rid of the green.

If it is a sponge, I'd remove it. I have a colony of Zoa's that are being suffocated by a yellow sponge.

 

[cryotek74]

thanks everyone for the help. I'll take the frag and all the hitchhikers out tonight. I'll just cut off the zoa and glue to new rock.

If manual removal doesn't work emerald crabs are really good at cleaning it up

A single tunicates has 2 openings, however, they can be solitary or colonial. Sometimes in the colony, each individual has a siphon all to themselves and then also shares a common siphon with the rest of the crew. There can be tissue over the colony to cover of their individuality, so that they look like a single blob with multiple siphons. In a sponge all those siphones belong to the single animal. In a tunicate, the siphons all belong to multiple individuals under a single cape.

Sea squirts got their name from their very forceful ability to squirt water and retract. Some sponges can sneeze, or clear their filter system if clogged, but it's not the same swift motion.
