Sustained in that temp range will cause issues if maintained too long. Aside from lower dissolved O2 levels at such temps, the fish's osmotic regulatory systems will be affected due to temperature effects on hormone production, enzyme stability, and the regulation of amino acids. Some species also can experience a breakdown of cholinesterase that will manifest into neurological impairment.
Black crappy lethal temperature?

Your probably best to ask that of the arrowana people, but remember that the general consensus is to not mix the two, for very good reason. Crappie are a beutiful, interesting fish, but are much lower temp oriented than some other natives. When the ponds here go dormant, for the most part, you can still catch crappie. I've caught them in temps as low as 38 degrees, water temp. It's best to get them their own home.
If your dead set on doing something like this, I would definately recomend that you look at a different centrarchid. Maybe a warmouth? I don't think you'll be all that sucesfull though, as you can't really meet the needs of both arrowanas and centrarchids in the same tank, much like you can't mix the needs of trigger fish and discus.
Oddball, are you a scientist of some sort, or an amateur icthyologist? Your knowledge is pretty advanced!

well guys... i have the crappie in with my jar for over 3 months ...i end up eating all the crappie cause it cost too much to feed all (6)15in crappie and (4)6in in there..lol
3 months is not an extended period. The heatwave last summer caused the lake population to abandon many of their nests. Although it's uncertain whether the eggs suffered from the heat and died or if the adults simply abandoned the nests to seek cooler water deeper in the lake. We do know that the number of fry normally found in the shallows was significantly lower than observed the previous year.
What's the temp in that tank?
