i posted my experience because it seems that mine is turning around, from almost dying to getting better. your earlier post was exactly what i had mentioned, extending less and less. so i think my reply that i have gotten this one to start extending more is a pretty viable post.
also from what i have read and understood the short tentacle versions fair much better than the long tentacle ones.
while you're at it, why not just yell at everyone who has any corals or fish because they were pulled from the ocean at one point or another as well. and im sure plenty of them died before the keys to success were figured out as well. it sucks that most of them will die, but without people trying, there is no way to figure out how to properly keep them so that they can live in our tanks
