Angelfish Tank Setup

Angelfish are captivating freshwater fish known for their elegant fins and distinctive appearance. Setting up an ideal tank for these graceful creatures requires careful consideration of their habitat, water conditions, tank size, and compatible tank mates.

Select tank size and shape

Choose a tank with a capacity of at least 20-30 gallons for a pair of angelfish. A taller tank is preferable over a wider one, as angelfish have a vertical body shape. If you plan to keep multiple angelfish or a community tank, consider a larger tank, around 55 gallons or more.

Gather equipment

Collect the necessary equipment, including a suitable filter, heater, thermometer substrate ( gravel or sand) , decorations ( plants, rocks, driftwood ) water conditioner, and a testing kit for monitoring water parameters.

Set up filtration and heater

Install a good-quality filter that provides adequate biological, mechanical, and chemical filtration. Angelfish are sensitive to ammonia and nitrite levels, so maintaining water quality is crucial. Use a reliable heater to maintain a water temperature between 78°F and 82° F (25.5°C to 27.8°C)

Filter and heater are easily available on Amazon.

Add substrate and decor

Rinse the chosen substrate ( gravel or sand) thoroughly to remove any dust or debris before adding it to the tank. Decorate the tank with tall plants, rocks, and driftwood. Provide hiding spots and vertical spaces for the angelfish to explore.

Dechlorinated water

Fill the tank with dechlorinated water. Use a water conditioner to remove chlorine and chloramine, which can be harmful to fish.

Cycle the Tank

Cycle the Tank before adding angelfish, cycle the tank to establish a beneficial bacteria colony that will help break down waste. This process can take several weeks. You can cycle the tank using ammonia or by using established filter media from a mature tank.

Monitor water parameters

Regularly test the water parameters, including ammonia, nitrite, nitrate, pH, and temperature. Aim for a pH level between 6.0 and 7.5 to replicate their natural habitat.

Acclimate the angelfish

When the tank is fully cycled and water parameters are stable acclimate the angelfish to their new environment and float the bag containing the angelfish in the tank for about 15-20 min to equalize the temperature. Gradually add small amounts of the tank water to the bag before releasing the fish.

Feed properly

Offer a varied diet of high-quality pellets, flakes, and frozen or live foods, such as brine shrimp and blood worms. Feed them multiple times a day, but only as much as they can consume within a few min to prevent overfeeding and water quality issues.

Observe and maintain

Regularly observe the angelfish for any signs of stress, illness, or aggression. Perform routine water changes ( about 20-25℅ of tank volume to maintain water quality. Keep the tank clean and well-maintained.
