can anyone settle my mind i purched a tigerfish [datnioides microlepis] yesterday,did do some research as i always do but not sure if this species needs a freshwater setup or brackish.can anyone please let me know the best conditions are. the reason im not sure is because theres a total number of 5 species in this family.im pretty sure its the microlepis because of the number of black bars hes got best regards mick
