whats the right size tank for a jack demsey?

Answer 1

Minimum of 40 gal

Answer 2

An adult Jack Dempsey cichlid can grow up to 10 inches (25 centimetres) long and must be provided with plenty of space. Do not house it in an aquarium smaller than 45 gallons (170 litres).
If you plan to keep it with other fish, the recommended aquarium size will naturally depend on these species as well.
In the wild, the Jack Dempsey cichlid inhabits densely grown waters. Plants are however often avoided in Jack Dempsey aquariums, since the Jack Dempsey likes to eat live plants and can destroy them. You can instead use flowerpots, caves, rocks and wood to form natural borders in the aquarium and make it possible for the Jack Dempsey cichlid to claim a limited territory. Since the Jack Dempsey cichlid is fond of digging, you should avoid substrate with sharp edges. A barren bottom, or a very thin substrate layer, is also unadvisable. Heavy objects that can injure fish if they fall should be placed directly on the glass, since they might fall when the Jack Dempsey cichlid digs around.
Temperature Tolerance:
The lower lethal temperature of Jack Dempsey was estimated at 8.0°C by Shafland and Pestrak (1983), upon which they placed Jacksonville as the probable northern limit for their range expansion in Florida. Jennings (1986), observed Jack Dempsey dying from cold stress, in a small creek in Alachua county, at 10-11°C.
