ornamental shipwrecks

[qxcontinuum]

Hi again one of my stupid questions;

Do those nice ornamental shipwreacks full of holes can do harm in a reef tank.
They are made by sort of a plastic.
I have a nice ship with holes and hambers which can make a great addition to my fishies intimacy as well for some corals

It should be fine in your tank. Some people use them.

Most likely it will get covered in algae, but they do look pretty cool if you get the high end ones.
