My group of channa andrao ranging from about 7cm to 8.5cm (not including tail). I've only had them a few weeks so some of the photos show a bit of fin damage preseumably from transport, which has now healed up. They are very sweet and sociable with each other so I will be quite sad assuming a pair will eventually form and the the spares will have to go.
Before I got them I didn't realise how often and how quickly they will change their colour. The last pic shows a female going quite pale as two of them have a minor scrap.
