That's another thing I'm a little worried about....everyone keeps talking about finding "bad" critters, and needing to remove them before placing the rock in your tank, but I don't know what these things look like

I'm only a beginner and have no clue what I'm looking at... it all looks cool to me :tongue: Chances are, in a year, I'll be raising a whole 90 gallon filled with mantis shrimp
