What methods do people use for getting rid of unwanted pests? Especially the ones that only come out at night when your not watching!
Depends on the kind of pest. The way I'd get rid of a zoa eating nudi is different than an aiptasia.
I've ordered a crab trap as I've noticed a fair few of them mooching around on my live rock, a few are stripping the coraline off parts of it. Im going to bait it with a mussel and see what comes in for a nibble
