Standard snakehead setup , big tank temps 72-82˚F; pH 6-7.5, that species gets about 12", and they are jumpers so make sure you have a good cover however they need to have access to the air for breathing so leave air space in the top of the tank, and low light (unless you get a blanket of floating plants like I do) you'll need heavy filtration, I don’t like HOB filters with snakeheads because I use duck weed as a floating cover lots of hiding spots, and it gets mixed up in into the filter, so I like big canister filters or sump...
they are a predatory fish, meaty foods, (feeder fish shrimp, ect) and that of course messes up the tank especially as they get bigger, I haven’t kept this species but i'd assume it grows rapidly s many snakehead species do...
That’s the basic’s
Next time you really research BEFORE buying the fish, hope you have a BIG tank!
