what is up with this?

Was watching my Polli and I noticed his anal fin was inflating and deflating. Happened like 10 times...is this normal? Looked weird!!! Thewhole little fin would puff up like a ball really fast, then go back to normal after a second or so.......

Managed to kinda grab a picture....looks more like he us cupping this fin. First time I saw it, he was "cupping it the other way so it looked like it was inflating. Still kinda weird. He gets it all stretched out and distorted

Very normal, that is a reflex of the anal fin in males which they use during spawning to cup the eggs released by the female polypterus for a brief moment allowing him to fertilize them, then releases the eggs to let them scatter about.

Here is a clip I recorded of a delhezi I used to have showing this behavior:

Thanks very much Cohazard. Learn somthing new every day. Tried to find it on Google....but "inflating" was not the correct term to use!!

 

[Cohazard]
