Advice for a newbie with a marine tank

[mseepman]

Usually you can take out that piece of rock and coax the shrimp out of it with a baster and some fresh water. Be cautious as it would be painful for him to smack you like he does the snails.

Simply squirt water into each hole and be prepared to catch him in some salt water so that you can decide what to do with him. They are great in a sump.

Hope that helps.
