This appeared in my tank a while ago and can’t be bigger then an inch long. Tried to google what it is but can’t find anything. I only house green bubble tips anemones so not sure how it’s got into my tank.

Glass anemone. Typical hitchiker and known to multiply quickly in some situations.

It's a type of aptasia, not good, they multiply incredibly fast, aaaaaand sting as they go. the problem with these is they can irritate your stock to the point that they will shrink and not feed untill they die.
