I'm in research mode planning to establish a 40Gal FWLR tank.
I haven't had a SW
tank in over 30 years so things have changed a bit.
My question is about 'pests' that may come with LR
. Several sites talk about cleaning the rocks during the curing phase, which makes sense to me, but then they talk about removing pests such as bristle worms, and mantas shrimp.
What exactly is a pest and why? I can certainly understand something being a pest if it harms desired tenants but what harm can a bristle work do... I don't know anything about them.
What type of critters do I have to be looking for?
I am not going to setting up a reef tank, just live rock and fish.
