Coral Banded Shrimp??? Worth it???

Whats your opinion on them? I found a ad on Craigslist for 2 urchins and a coral banded shrimp for 10$. Is That A good deal? Will The Coral banded Shrimp hurt anything in my tank?

i Have a 75g. GSP's, Monti, Kenya Tree, and Frogspawn. Along with 2 Damsels, An Algae Blenny, 1 large star serpent, and 3 babies, and around 200 assorted Snails.;D;D

Should I buy???

 

Xcellent offer, but I don't know if they ship well...

 

Its about a 15 min drive from my house so id pick up

 

I have had a coral banded in all my tanks over the years. Never hurt anything.
What kind of Urchin?

 

2 Spiny Black ones

 

I have one in my tank also. No problems at all. A color and excellent addition to your cleanup crew as long as he's the only shrimp in there.

 

He will be my first and only shrimp

 

They are cool but they do knock your corals over. They eat coralline also.
But I have read that when the eat it and poop it out that it actually spreads the coralline more. They are super cleaners IMO. I had 2 in a 90 Gall Aggressive I had a couple of years ago.

If you touch the spines that fall off --your fingers will have a purple line on it for a few minutes. There spines are poisonous -So don't touch them!

 

I have had them with other shrimp with no problem.
I have read that sometimes it can be a problem if you get a real aggressive one.

 

Yeah, I heard the same thing with having them and other shrimp.
