Native to India. Temp is aggressive and opp feeder. Sharp teeth will take chunks off fishes when the yerelli gets big enough. Max size is know to hit the 2-3m mark, when it gets there, its going after you if u go into the pond. Natural habitat is fast flowing murky river. One of the documentary claims that research have should that they eat dead human carcasses thrown into the river for burial. Bagarius are very inactive fishes, know to just park at the bottom for long time. there are various variety of bagarius so make sure u getting the right one.
Would not recommend keeping it unless u have a pond for it and light colored so you can see it at the bottom.
Growth rate I'm not sure as I have not kept one. But should be slow compared to rtc.
Some have claim that theirs are not aggressive, imo, its more like not yet.
Hope this helps.
