hey guys gals,i got a few new things that poped up in my tank last night,i think its so freaking cool how i didnt buy anymore things (LR) and things just seem to "hatch" up,my daughter and i were looking at my tank and she stoped very tiny things on the sand,by their movement i could only guess baby shrimp but they were light green...is that possible? sorry no pics on that cause my camra wouldnt pic up a centermeter long thing like that....secound thing in the tank i saw were probably a bit longer then a centerneter long,maybe fuzzy,not too sure,green warm on the back wall of my tank.....again no pics cause thats far back in my tank and they are tiny...sorry,however, here are pics of a new little guy that i hope you all thell me he is ok,a brown urchin,other then calling him a brown urchin,i have no idea if he is good or not,mind sheding some light guys? oh and also can you guys tell me a bit bout this hermit,my daughter calls him hermie john over at reef cleaners sent him when he sent the snails,thanks again for the long winded wait now for the pics

long spiney urchin and a blue legged hermit is my guesses.. I believe the urchin will eat coraline algae

as for the other things.. the shimp like thing could be a manits (need pict) or a nudi

[nightfire76]

can the urchin and hermit be reef safe? and as far as my caroline algae goes,i notice that even my snails eat that,had a good bit til they came in lol as far as the shrimp and worm goes i can only wait til they get to the front glass and get bigger to take a pic or tell better

[sambrinar]

yep both are reef safe, I have 2 blue legged hermies.. the only prob with the urchin is it will walk away with frags, crabs, snails, thermometer.. LOL but shouldn't eat any coral or anything... there are fish that eat them, so be aware of that k?

[nightfire76]

ok though i think two of the 4 fish i plan on adding might be trouble lol a flame angle and a lemonpeel

The crab looks like a pretty standard blue leg. Commonly used as cleaners in reef tanks. Like all crabs and opportunistic feeder, but I wouldn't worry about him at all.
The urchin looks similar to one I had appear out of LR once. He grew really fast and I gave him to the LFS since he was in my 20g and getting pretty but but he never really caused any problems so I wouldn't worry about that one either.
The other stuff, I don't have a clue without a pic.
