My group of Betta sp. cf. rutilans green seem to have completely recovered from a previous oodinium infection. However, with an improvement in health has come an increase in aggression, particularly as it appears I have at least two receptive females in the tank. In fact I actually caught a pair embracing the other day, though no eggs were produced due to the pair being constantly interrupted by their male siblings.
This group has always shown high levels of conspecific aggression. Because oodinium can be triggered by stress, my plan is to maintain as low stress an environment as possible. Already I have the group in a larger tank than they were previously, but you can see from the above picture that this hasn't done much to help.
Because I am not planning on working with this species further - besides maintaining this current group to the end of their lives - I thought it would give me an opportunity to create a biotope style tank that mimics more closely than any of my other tanks, the type of environment these fish would inhabit in the wild.
Hopefully this will be taking shape over the next couple of weeks, and I will be posting up photos as I go along.
