They can come in on almost anything
I have tried dry rock before, utter fail. Never again
If one can't take that risk[worms on real rock], a different hobby is probably a better deal for one
Definitely agree! You just have to embrace some of the pests, and add good quality LR. Try to keep the corals so that you can remove them for dips or treatment. Try to avoid what’s possible and work through each situation as it arises. Pests are going to get in. Many of these things are microscopic and near impossible to keep out. You just need to deal with them one by one.
