Does he tolerate warmer temps better than when younger?
Also Do you think paddlefish should always be maintained in a species only tank?
Also do ya know how they tell if it is a dink or not?
They are very tolerant of temps, outside they lived quite well in water that was warm to the touch but well aerated, temp was probably high 80's, low to mid 70's is probably close to optimal, I would think that really warm water would be detrimental over a long period of time.
As for a species only tank, that is probably not necessary, I keep mine with several coolie loaches, cory cats, and several ottos. They will swallow small fish that hover in mid water but I see no reason why they couldn't be kept with non aggressive fish.
Feeding is the most important part, any fish that would out feed the paddlefish would be a problem. Paddlefish do not digest all of thier food and they are as nasty if not nastier than fish like koi carp, the food goes through them and needs to be removed. Scavengers do a pretty good good job of eating the partially digested food.
Right now he is alone other than his scavengers... Even this dwarf paddlefish needs a large tank, a foot print of 8 by 2 feet would seem to be a minimum to me...
