Sorry to bother you, but I have never observed neither the behavior or a pair or of 2 males and I can't understand what I'm watching.
The most important thing I'm trying to understand is if this can turn into physical aggression.
Is ORA still breeding them? I haven't seen any of their tank bred in a couple of years.That's cool I recently got a small ora one. So I know it can be done. Real timid and got it eating live brine shrimp. Yes you could vent them to see their sex. I imagine it would be hard to see because their black though. Could you take the rock out and trickle air over the eggs from an air stone take the adults out of the equation? Get them in a fry only set up with loads of copepods maybe.
Yep got one on LA. but their sold, out back in stock, sold out... gota stalk it. Sorry it was Biota had them and also on their cite. My mistakeIs ORA still breeding them? I haven't seen any of their tank bred in a couple of years.
The Biota ones are the ones I breed.Yep got one on LA. but their sold, out back in stock, sold out... gota stalk it. Sorry it was Biota had them and also on their cite. My mistake
Difficult to tell. But there is certainly some rivalry. I would keep a close eye on them.
The babies are sooo cute - kaliA long time ago far far away (in the early 90s, back in Germany) I bred a few batches of Marine Bettas (aside from a few thousand ocellaris, percula, and clarkii anemonefish).
One of my later Marine Betta pairs. The male (front) is actually one of the babies I raised on my first attempt. The female is wild-caught.
Male with eggs:
12 weeks old juvenile
Fosser & Nielsen came by to take a few pictures for their book series:

Description of Fry: completely black before settlement, post-settlement body white, head and fins black. Shape nearly like the adults, most notable difference is that the tail fin has a straight end. Behavior of settled fry: pivoting around the eye like adults. Very slow eaters.
Extremely high losses due to sudden fright syndrome during and after metamorphosis.
Grow-Out Tank Details
Temperature: 26 °C
Size of Grow-Out Tank: 60 L
Substrate Details: coral gravel
Other Tank Decor: live rock
Filtration Details: hooked up to parent system
Lighting: 2 fluorescent bulbs
Lighting Cycle: 12 h
Water Changes: hooked up to parent system
Size at Transfer: 7 to 8 mm
Age at Transfer: 35 days
Grow-Out Feeding Details
Food Types: live brine shrimp and whatever there was on pods. Frozen food after 20 weeks.
Feeding Schedule: at least 3 times a day
Developmental details:
The larva has at the beginning a round body cross-section and is mostly dark-colored.
During the second week, the body shape becomes higher and laterally compressed and the coloration becomes darker.
After settlement, the appearance changes dramatically: the body sides turn completely white, while the head and fins are black. This change happens quite literally overnight. From this point on hiding places are required.
After 40 days (~8 mm TL) white dots become visible in the black areas.
After 12 weeks (~20 mm TL) the eyespot on the dorsal fin starts to develop. The white area on the body sides starts to shrink.
After 27 weeks the first fish lost its white area completely.
That is such a drag. I think the shipping companies must be responsible for a large portion of the fish being sold dieing.And another DOA...
