If you could get some closer up pictures/videos of the two(that blue/MG and the Blue EE....the white EE looks feminine to me, its just those too seemed a little too manly IMO), I could probably tell you if they're male or not. Hold up a little mirror if you can too, to see how they react and get a good look at their beards/ventrals.
Will do! They are both gorgeous fish, but I don't want more boys.
It's tough to get the blue marble to flare- s/he a pretty laid back fish. When s/he does, it is beautiful. The blue ee flares more, but no on seems impressed. I've had a few sprint chases, posturing (awfully funny looking) but no nipping.
The one crisis: Two of my 5 corys were lying dead on the bottom of the tank this morning
I've lost 2 others b/f the tank had the girls. I noticed a marked difference in their behavior after I introduced the bettas- they seemed panicked. A few of the bettas were just too interested in them (the yellow betta is just smitten) but not in an aggressive way; just in a "are you another betta?" way. SIP, guys.
