This is a socalled Blue bleheri (because of marketing reasons?). In Germany, it is called either Channa spec. Assam or Channa spec. Asia Blue. Is has not so much to do with Channa bleheri! It is a mouthbrooder, Channa bleheri is a nest brooder. It is an undescribed species which lives in the state of Assam and in its neighboring states. It seems to be the smallest channa found. You can find breeding reports on both species in the corresponding Aquaristic -> Species section here on this site. The picture is a contribution of a British pet shop called Goldenline which is online. We want to encourage the visitor to shop there because of their support of us :-) Thank you Steve McAlear for your contributions.
