Below, is a 40 litre tank that contains a group of Betta coccina. To many hobbyists, I'm sure this tank looks like it's in dire need of a trim, but for a tank housing coccina complex species, it's close to perfect (admittedly I would like the water a shade or two darker).
These plants not only remove excess nutrients from the water column, but also provide valuable areas of cover, break up lines of sight, and encourage the growth of infusoria. All of which are important when breeding a territorial, and sometimes intensely aggressive, species of fish.
Many hobbyists only witness the true beauty of their wilds during courtship and spawning. With my planted tanks, I see it everyday. My fish are brilliantly coloured, and brimming with confidence in these set-ups. They don't need to feel threatened, because there is enough plant mass that they are safe from potential predators or aggressive conspecifics.
Hailing from Melbourne, Australia, I currently keep and breed a number of species from the coccina complex.
