From larger, already dead fish they can separate mouth-sized pieces only under difficultiy by strongly shaking movements. In densely populated drying pools, walking catfish are particularly indiscriminate in their choice of prey items, often seizing and consuming a wider variety of prey than what may normally be available.
Presumably not only the intervals play a role here between the spawning procedures after which a longer period leads to a higher number as described in this case with 5, eggs at the beginning, because even if such a high number of eggs the female can theoretically eject in the course of a day, because it is already available, it is not automatic that she must deliver them all.

This wanting to avoid water changes and feeding too little, can be fatal for other fish with the large greed of the animals. Walking catfish are sensitive to cold temperatures lethal temperature is 9. The experiences introduced here can presumably be also used for other Clarias species, if not even transferring it to some other catfish families or motivating to think a little in this direction.
Due to the giving of rich living food, especially due to the induceing of fresh water, the lowering of the water level and then the increased temperature, the female soon visibly gets spawn and with the light preferably turned off the animals start courting. Either one is safe to have a pair already in this size or one has to found for itself such a pair from a group of either four or five animals, going beyond what is required, or sufficient with the fish already there.
This sensitivity has limited their migration north into colder areas. Originating in South-East Asia, C. batrachus, the walking catfish, has been introduced throughout the world for the purposes of aquaculture and as an.
