You can always just emulate the look of a blackwater tank without having the exact conditions. It seems like unless the fish is wild-caught or a particularly sensitive species, most of the commonly traded fish in this hobby are pretty adaptable. You probably just wouldn't expect to see any spawning happening.
Since I have been procrastinating on water changes, I decided to get my camera out and take some more photos. I can never have too many photos haha.
My persephone are playing at being 'wild' fish at the moment so are refusing to let me get any decent shots of them. This was the best I managed last night and it was only when I was about to put the camera away that I got it.
My rutilans are a funny group of fish. There are around 15-20 fish (some over two years old) in a 10 gallon tank, and yet most of the time I can't spot a single one of them! It's only if they think I might be feeding them that they bother to grace me with their presence. However, they are beautiful so I will forgive their lack of loyalty.
My coccina group are doing really well. I doubt the dominant male and female will spawn with the other male in there, so I probably should get him out at some point. They tend to be a lot more prone to striping up than my other wilds so it's hard to get photos of them in full colour. This is the dominant male after he finished off a blackworm. I got in quick before he could clamp up.
You can see why they are also referred to as 'Wine-red betta'.
This is their tank. The tannins show of their colours nicely, and the extra java fern provided the female and smaller male with more cover as this species can be rather aggressive at times.
