Aquarium Size

Choose the right size tank for your Jack Dempsey fish. They are big and need lots of space to swim. Use a 55-gallon tank for one adult Jack Dempsey, and add 20-30 gallons for each extra fish. This gives them room to grow and be healthy.

Bigger tanks are good because they keep the water stable and fit better filters. A larger tank also lets you add more rocks and plants for a natural look. Choosing the right tank size ensures your Jack Dempseys have a happy and healthy home for a long time.

Equipment

Filtration

Regularly clean and maintain your filter to prevent waste buildup. Check the flow rate and replace or clean the filter media when necessary. Proper filtration keeps the water clean and helps your fish stay healthy.

Heater

Choose the correct heater for your Jack Dempsey fish tank. Use a heater with the right wattage, about 5 watts per gallon. Put the heater near a spot with strong water flow, but avoid disturbing plant roots or causing sudden temperature changes. 

Check the heater often with a thermometer to keep your fish safe. Adjust the heater when the room temperature changes to keep your fish comfortable.

Plants, Substrate, and Decor

Plants

Choose fast-growing plants like hornwort, anacharis, or java ferns. These plants provide hiding spots for your fish and help keep the water clean. They also add oxygen to the water and create a balanced ecosystem. 

Before adding plants to your tank, rinse off any dirt, trim dead leaves, and check for pests or diseases. This will help your plants grow well and keep your fish healthy.

Substrate 

Jack Dempseys prefer sandy or fine gravel in their tank, similar to their natural river habitat. This substrate helps keep the water clean by supporting good bacteria that break down waste. Keep the substrate depth at 1-2 inches for your fish to search for food and maintain water flow. 

Use smooth materials to prevent harm to your fish and ensure their comfort. By choosing the right substrate and keeping it at the right depth, you can help your Jack Dempseys thrive in their tank.

Decor

When you’re getting your Jack Dempsey tank ready, you have a lot of choices. These fish are pretty and need a setup that fits their colorful personalities.
