I've had my pair of Betta sp. wajok for almost a month now. While my pair of Betta miniopinna that arrived at the same time have been frequently spawning, my Betta sp. wajok seem much more reticent.
Before today, the fish I believed to be the female of the pair, rarely coloured up. I did once catch her showing some faint vertical barring, but most of the time she displayed prominent horizontal barring and very washed out colouring. Unlike my other breeding pairs, the male and female rarely interacted. Often the female would remain out of view at the back of the tank, while the male was up the front.
Because this was proving extremely frustrating, I decided to make changes to their tank in the hopes of encouraging a spawn - or at the very least courtship.
I dropped the water level down to 15cm, and increased the amount of tannins by adding rooibos extract and IALs to the tank. Peat moss was also added over the aqua soil substrate, while earlier this morning I picked up several pieces of 'Mekong River Driftwood' from a store in the city.
Unfortunately, while my plan worked in that both fish have coloured up fully, it seems that the male is now being rather savagely pursued by the female. You can see almost half his caudal is missing in the above photo. Since then, his anal and ventral fins have also been badly torn and at this point I am considering separating them as I only recently lost my Betta brownorum male to his hyper-aggressive female.
All of my current breeding pairs were spawning within a week or so of arriving. I was rather excited to have the opportunity to work with a new 'species' in my fish room, and was hoping that these fish would prove as easy and eager to spawn as the rest of my stock.
Therefore, if anyone working with this species has any suggestions as to how I can get my pair to spawn, I would very much like to hear them. Also, if anyone is able to correctly sex these fish from the photo above, please do let me know. I was hoping a spawn would answer my question, but at this rate the male isn't going to have enough body parts left to reproduce!
Hailing from Melbourne, Australia, I currently keep and breed a number of species from the coccina complex.
