Why are nudibranch bad for my tank?

[smithce79]

A few days ago I found a nudibranch on my tank and a lot of people from this forum told me to take him out of my tank because they are bad.

I put it on my refugium, because I dont want to kill him, but I would like to now if Its true that they are bad and why.

No problem

Each nudi has a different diet but most eat some type of coral

Even the ones that easy algae need lots of algae, if not they will die and can be toxic upon death.
