Minimum Tank Size
Jack Dempseys have the potential to grow quite large, around 10 inches, so they need a space fitting their size. Go for a minimum 55-gallon tank to let them stretch their fins. Bigger is always better, giving them room to be the bossy fish they naturally are without bumping into everything.
Water Parameters
Keeping the water just right is key for these cichlids to live their best life. Here’s the lowdown on what they need.
Temperature
You want your Jack Dempsey to feel cozy in temps between 72°F and 82°F—they don’t like it too hot or too cold.
pH Levels
Aim for a pH sweet spot of 6.5 to 7.5. This range is comfy and feels just like home for your finned friends.
| Parameter | Value Range |
|---|---|
| Temperature | 72°F to 82°F |
| pH Level | 6.5 to 7.5 |

When it comes to the stuffy their tank floor, sand or fine gravel does the trick. It’s like a soft mattress for them to dig into without a scratch.
Plant Compatibility
Jack Dempseys have a reputation for being roughhousing little diggers. Tough plants like Java Fern, Anubias, and Amazon Swords can endure their antics. If you’re worried about your flora getting messed up, artificial plants might be the way to go.

Essential Equipment
