Dino problem (I just want it gone)

[shackman]

My tank is about 7 months old and I'm having a Dino outbreak. I only have one frogspawn, three fish and some snails, shrimps, and crabs. nothing two expensive so I want to know what I should do to kill this problem completely before I do get some expensive stuff in my tank. I would like to save my live rock.
