Ok,I broke my 75g in half when I was moving so I want to permanentlly move my hydno to my 10g nano. Question is on average how long are its sweeper tentacles having never seen them myself,I was warned when I bought it but I never had an issue in my 75.
Thanks in advance

Anything within 2"-3" would be at risk. My observation is that other coral grows much closer than that, but when the attack comes everything within 2"-3" will be killed.

Thank you,I'll go 5'' to be safe. I just had these visions in my head of 12'' sweepers wiping out my whole tank lol

Whoa! 2"-3"? I better move mine then I think.

How often do they extend the sweeper tentacles then? I have had mine for a while, its about 6"x4" and quite close to a bunch of gorgonians. The polyps or tentacles are always out but never more than like 1/2" or so. I guess I better be careful!

Ive had mine about a month and have never seen them extend past 1/2 inch either. But alot of people including the lfs say its a bad stinger with long tentacles,better safe than stooopid I allways say

Oh I totally agree. I knew they were very bad stingers, I just did not know they had long sweepers. Mine just always looks really fuzzy, like it has thousands of polyps and then once in a while they get what I thought was really long at about 1/2"...I can't imagine 2-3". That would look so cool though.
