theres nothing brave about it really...
the sturgeon is way bigger than the snakeheads... and they r marulioides... the least aggressive species... they rnt very aggressive at all unless it fits in their mouth...
as for the goldfish... they r way to big for the snakeheads...
the temp is just over 26 celcius... sturgeons do require 'cold water' but not really. what cold water implies is oxygen rich water... which i have due to my 2 giant streams of bubbles...
and i dont like the sturgeon my friend bought it when the tank was still empty and now since its winter I cant get rid of it cuz going from 26 celcius to a pond thats like 10 celcius would be murder... so i have to wait till summer... grrr
