These are not bleheri. They are channa sp. Assam or lal cheng shops call them "blue bleheri". The real bleheri has orangered spots in the tailfin. The lal cheng are subtropical like bleheri,aurantimaculata stewartii,... they dont want the water too warm. permanently high temps cause early death. regards brucki PS: give them more hiding places, and they will show better colours
