The male every now and then show these inside blue gill

My question is that mating behavior for this fish?

I'm not quite understanding your description. Are you referring to him "flaring"? If so, that's aggression.

Chris123

Yes just like a betta would but with blue gills

He doesnt do it often so im not worried about im curious

Shawnie

if he is doing it to other fish, its aggression and dominance showing..if he is doing it towards a female con, hes showing her his muscles and proving to her hes the man!

bolivianbaby

It's kinda dominance/aggression. If there's no fin-nipping or damage, he's just "showing off" his big-badness

Chris123

He does it to the female

No damge what so ever

Good to know
