Do you have to glue coral in aquariums or will they latch on by them selves ?

Question

are there any good or bad points in glueing coral and not glueing them?

Answer 1

first of all you dont just grab elmers glue and get kicken you need to buy a special aquarium glue and glue it to a coral holder that should solve your problem

Answer 2

yes it is good to glue corals to the rocks to avoid them fallin or being knocked over by powerheads or fish or hermit crabs.

but gluing has downsides you cannot rearrange just the coral you'll have to move the entire rock!

there are special glues that are for use in reef aquariums.
