Water Conditions
Jack Dempsey fish like warm water. Keep the water temperature between 75 and 80 degrees Fahrenheit (24 to 27 degrees Celsius). The pH level should be between 6.5 and 8.0. This means the water can be a little acidic or a little basic.
Change 25% of the water every 2 weeks. This keeps the water clean. Use a good water filter to remove dirt and waste. A canister filter is a good choice for their tank.

Jack Dempsey fish like to hide sometimes. They feel safe in caves or behind rocks. You should add hiding places in the tank. Use rocks, driftwood, or special aquarium caves.
