After the past several day, I found this in my tank. Base on what i read, it must be Aptisia, right?
What does it do in the tank? I saw it release 1 small baby as well. Good or bad?

If bad, how do I get rid of it? Cheers!

Yes it's aptasia. It is a nuisance in the aquarium and will take over. It can sting your tanks inhabitants causing damage and is IMO unsightly. To get rid of them you could purchase one of the commercially available control products, or you can use a hypodermic needle and syringe to inject lemon juice into their mouth this will get rid of them and works very well (I have used it many times and no more aptasia).
