The other day I decided to move my Betta sp. apiapi tank up onto the top shelf. Because it's only a small tank, I decided that I'd drain out 3/4 of the water and then just move it from the sideboard and up onto the rack. This saved me having to try and net everyone as there is quite a large group of fish in there.
The tank fits nicely beside my Betta persephone tank, and I'm hoping that with the abundance of natural light that comes through the clerestory window, I won't have to use any artificial lighting overhead.
The original pair spawned earlier today, so it seems like they haven't been at all phased by the move. Some of the sub-adults are so close to spawning size now. Be exciting if I could get an F2 generation going so soon.
I was thinking with the large number of juveniles present in my Betta hendra tank, that the original pair would show more reluctance to spawn. However, several days back, the pair gave me the privilege of watching the entire process from start to finish. The eggs hatched today, and as usual the male is very dedicated to their care and protection. Neither his mate nor his juvenile offspring dare to venture anywhere near that side of the tank when he has a nest to defend.
The biggest of my Betta miniopinna fry have started taking freshly hatched artemia and grindal worms. While I have not witnessed the pair spawning since I stopped treatment for external parasites, the male almost always has a nest, and spends much of his time inside of the film canister. Of course it is in such a location that I can't get a good look in - these fish never make anything easy!
Unfortunately, it looks as though my treatment for ich in my Betta brownorum tank did not work. While there are no longer visible parasites on the female or the male sub-adult, I found a juvenile with a couple of distinctive spots on her head, and so I will be turning up the heat in their tank for a further couple of weeks. I suppose at least it is not the dreaded oodinium.
Also, it turned out that my Betta sp. wajok are indeed both male. Therefore, the replacement female offered by Hermanus will be a very much welcome addition. No wonder my pair were so resolute in their refusal to spawn.
Otherwise, there hasn't been much else to report from my fish room. I've been meaning to write up a couple more informative posts, but have been suffering with a bout of writer's block. Also as most of my tanks are in rather atrocious condition, there has been a severe lack of photos. I intend on giving them all a good clean this week, so there should be some further posts soon.
Hailing from Melbourne, Australia, I currently keep and breed a number of species from the coccina complex.
