Since it's a new year, I thought I'd post a brief overview on what's happening with the various species in my fish room. Unfortunately, I only have a handful remaining from the coccina complex. However, I definitely haven't been short on fry from those species I do still own.
Betta sp. apiapi - Along with the original pair, I have at least a couple dozen juveniles and fry growing out. The male has a group of fry that are almost fully free-swimming, while the bigger juveniles are starting to develop their adult colouration.
Betta brownorum - Along with the original pair, I have maybe a dozen or more juveniles and fry growing out. Spawning activity has ceased amongst the parents and the male has become much more shy of late. Some of the bigger juveniles are starting to develop their lateral spot, and I'm starting to be able to get an idea of genders with a couple of them.
Betta hendra - Along with the original pair, I have at least a couple dozen juveniles and fry growing out. The bigger juveniles are starting to develop adult colouration, and should be sexable in a few more weeks. Both male and female have been showing interest in each other, so I am anticipating another spawn soon.
Betta persephone - There has been some spawning activity from the dominant female and one of the males over the past few weeks. Eggs are either rarely produced, or almost always eaten/abandoned shortly after spawning. However, I did discover a single fry in the main tank earlier today.
Betta sp. cf. rutilans green - Unfortunately, this group of fish have been suffering from recurring oodinium for the past few weeks. At the moment they are undergoing a 14 day treatment with 'Seachem Cupramine' and I will see if this has any effect. Because of the oodinium I will not be attempting to work with this group of fish any further. Hopefully in the future I will be able to find a replacement pair of this species.
Hailing from Melbourne, Australia, I currently keep and breed a number of species from the coccina complex.
