Good or Bad???ID needed

[NoobieNemo]

is this crab good or bad?he has 4 legs...and he has two pinchers...

and what is this blue thing?

 

[jasonross]

first looks like a red mithrax crab.. could be good or bad just depends on the inividual crab they could pick a corals ect. second looks like a feather duster not 100% maybe if you can get a better pic

I agree on the crab, good or bad depends on how you want to look on it.
Second photo I believe is a tunicate. Look closely and you can see the second opening(s) on the sides.

yea the blue thing is weird...it is clear, with very blue strings in it...the ends are open...

we like the crab...

Right spot ID on the first.

Second is a tunicate/ascidian/sea squirt, I believe clavelina. Do a search either in this forum or the new reefkeeper's for a picture.

Look forward to finding more red mithrax and probably quite a few porcelain crabs, too, as time goes on.

 

[NoobieNemo]

coyote...are you saying that you can't wait to find them in a good way or bad way?

 

[coyoteseven]

I like them... the reds do a better job on algae than my snails or hemits. The porcelains are just cool to watch, fanning their 'antennae' to catch their meals.

the second loks like the tail of a shrimp

I have the crabs twin in my 12g nano...he's great...hangs out everywhere..scavanges around..sometimes hangs out with about 14 trumpet coral polyps, occasionally near the GSP and likes to mull around my mushroon rock. Gets along well with red lip blennie. Keeper in my opinion.
