Got a hitchhiker or unknown critter?? Check here for an ID

[WindeyD]

Bad picture but can someone tell me if this is reef safe? Looks like a brittle star...

Yep brittle star

 

[Lionfish Lair]

I know what he is I just thought I would post for others. This is a coral eating fireworm. REMOVE at all costs but do not touch.

Sweet! That's a for real one!!! I know you know that, but I think yours is only the second one I've seen removed from a tank!

Yes, this is an old post, but I didn't see it before. It's purrrrrrrdy!

How can you tell difference? I think I may have some these but always thought they were bristle worms.

 

[Lionfish Lair]

It's the yellow stripes on the dark color "background". I saw the other thread, yours aren't the same. If it were, you'd already be hearing your doorbell

 

[Berlibee]

Can you ID please. Thanks.

Just to be sure, these are not WORMS. They have legs, antennas, they walk very fast.

 

[Lionfish Lair]

It could be a sand skater. Serolid Isopod.

Alright, here's a stumper. I saw two of these floating around in the tank tonight. I managed to capture the smaller one. What the heck are these? They seem to have a sticky foot and tentacles like an anemone, but I only have one BTA in the tank. It's time to earn your keep, R2R! They look to be polyps of some sort, kind of like the larval stages of jellyfish, but I have none of those in the tank.

It might be a baby anemone.if I recall correctly they can spit out a baby if they are in great parameters

 

[Eckolancer]

I agree could be a baby anenome or possibly a majano. If it's majano toss them out now they will plague the tank in a couple months.

 

[AllSignsPointToFish]

I'm pretty sure it's not a Majano anemone. I was just really surprised to see two the things floating in the tank, and I was fortunate enough to capture one.

 

[AllSignsPointToFish]

Here's an updated pic. Definitely looks like an anemone. I have the little guy sequestered in a jar in the sump. I just don't understand why he was floating around in the display tank like that. Maybe a case of asexual reproduction by pedal laceration?

 

[Eckolancer]

Does it have same colors of your main one?

 

[AllSignsPointToFish]

No, it's clear. The parent BTA is green with fluorescent orange tips.

 

[domination2580]

Couldn't they start off clear and add they growth get their color? That one I'm not sure on. But I do know they can spit it the babies

 

[AllSignsPointToFish]

I would expect that they color up as the zooxanthellae population increases.

 

[AllSignsPointToFish]

here is a better picture of one of our two new Hitchhikers. Are they good or bad?

Sea hare? Not quite sure.

 

[AllSignsPointToFish]

What do you guys think this thing is? I have at least one in the tank, and they appear to move around. Seems like some sort of snail or mollusk.

That would be a Limpet snail

 

[AllSignsPointToFish]

That would be a Limpet snail

Thanks! Looks like it's a good guy, no?

 

[Davesgt]

Yea most limpets normal just eat algae, I know I have a lot of them in my frag system and have no problems with them.
