as for the plastic cave, plastic is nowhere near as pourus as the rock, so it does not offer much for critters to move into. yes you can use it, but i personally wouldnt in my tank because i like to keep things as natural as i can.
hope that helps, welcome to the forum.
Thanks for the reply, Algae is not a problem in the tank it's kept under control and the water is crystal clear.
The rock I was given is not plastic but some kind of mock rock, don't have any corals yet but looking to get some soon.
