What is the proper name of those 2 long fins under the gills on the bottom of the betta Are they called "rays"? They sort of "balance" on them when they stop for a rest sometimes. Do they keep growing?? Val

Those are called the pelvic or ventral fins.

I don't think they keep growing, unless your betta's young that is. Dory's are actually different sizes from each other, but since they've been that way since I got him I assume they don't grow or change much.

From what i've searched out

They are ventral or pelvic fins.....and the fins of a male betta grow all its life

Thanks I *just researched the net, found out they are ventral, *found no reference to growing. *I am curious because Neptune continues his fin rot battle, but I am sure those fins are getting longer and longer. *They reach over halfway *past his anal fin - they are pretty cool. *Or it could be that I am looking for something to be happy about regarding his lovely assortment of fins. *His fin rot is confined to the caudal fin.

maybe he had a little damage to those ventral fins at some point and they've been regrowing?

I saw him resting today and the ventrals were right along the side of his body & they are as long as his little body...........so neat!! I don't think there was ever damage to them. I looked at a pic taken in Feb when I got him, and they are at least doubled!!

I see.. well, sounds like you just got a special Betta then.
