Any anenome is going to be hard to keep....you have to know what to feed them and how to care for them. Bubble tips might be easier to keep in some eyes, but man my sebae has been kickin for almost a year and is thriving. I don't think it would have lasted if we didn't take good care of it...but that goes for any anenome. I am not trying to pick a fight, so please nobody yell back at me....just wanted to say what I thought about this.
To tell you the truth, get what anenome you feel comfortable with, if it is a bubble tip then get that, if it is a sebae then feel free to get it. Just make sure you know about it before you make your big purchase.
