Post your cool hitch hikers thread
 

Little plate coral I found on some palys I bought, was about 5mm when I got it, about an inch now

I'm going to remove it once it sprouts a few more heads

Some sort of anemones that will be killed with fire if they move

What I believe to be a neon green toadstool, about 3mm across little white round blob behind mushrooms. Has neon green polyps when open

I'd look in to that anemone more. I don't trust those little buggers unless I know exactly what they are. I remember the first time I saw an aiptasia hitchhiker in my tank, I thought it was the coolest thing in the world.

I wish I had more to post, my tank is low on hitchhikers. Only 66 pounds of the rock in it were 'live', and I've broken every piece of coral off the base it came on before putting it in. The coolest hitchikers I have are two species of encrusting coral that are either porites or montipora. Well, used to be cool, now they're taking up too much real estate and are threatening to overgrow things I actually paid for.

My favorite hitch hiker is my smithii mantis shrimp. Got her as she was only 1/4" and now she's been with my for a year and half and she's 4" adult size. Very shy though, but I still like her.

Hitchhiker
 

Got this guy with the first piece of live rock I got about a year ago. It was bleached completely white and now has 2 babies beside it. I feed it brine shrimp once and a while and the odd flake.

What is that?

It's an evil anemone that will take over your tank!

It's an evil?
 

It's a rock flower anemone

That looks like something that could grow up to become delicious.
