Angelfish are freshwater fish with a lot of desirable and fascinating qualities. Goldfish are also freshwater fish with a graceful appearance. While some species of goldfish thrive in salt and freshwater, angelfish thrive only in freshwater.
Angelfish and goldfish cannot live together in the same tank because of their difference in origin and require different water conditions. They also thrive in different water and tank conditions, making it difficult for them to live together.
Besides having different water requirements, they have other properties that translate to the fact that it is not ideal to have them together in a tank.
Factors to Consider Before Keeping Different Species of Fishes Together
The consequences of keeping two incompatible species together in the same tank might be fatal. Predation, bullying, and general unrest are some of the results of keeping incompatible fishes together in the same tank.
Giving due consideration to some critical factors will help you make the right decision of the species to keep together. Some of these factors include;
- Temperament and general behaviors
- Feeding habit
- Fish Size
- Tank and Water requirements
- Lifespan and Susceptibility to parasite and diseases
- Tank Size
Water and Tank Requirements for Angelfish
Angelfish and goldfish have different water and tank requirements. The goldfish cannot thrive in the angelfish’s water condition, and the angelfish cannot thrive in that of the goldfish. Here are the water and tank requirements for the angelfish.
- pH: Angelfish thrive in slightly acidic, slightly alkaline, and neutral waters. The ideal pH value for the angelfish tank water should range from 6.8 to 7.8.
- Temperature: The temperature of the water is an essential factor to consider. Angelfish thrive only in waters with temperatures ranging from 78°F to 84°F.
- Hardness: The hardness of the water is also very crucial. Angelfish prefer slightly hard water, but they can also thrive in hard water because of their robust features. The ideal hardness value for the angelfish ranges from 30 to 80DKH, equivalent to 54 to 145PPM.
- Tank size: Angelfish do not like to stay in a choked environment that limits their movement. They prefer large tanks full of decorations. The tank for your angelfish should be as large as 55 gallons. Tall aquariums are the best fit for angelfish as it suits their body shape. They also prefer gentle flowing water as they are not very strong swimmers.
- Decorations: Like every other fish, angelfish like to have a series of decorations in their tank. Decorations like driftwoods, large broadleaf plants, and floating plants are suitable for their tank. You should arrange the plants vertically to simulate branches and trees.
- Substrate and Filters: Angelfish like medium-grade substrate and smooth surface gravel because they like to forage at the bottom of the tank. They also require a good and powerful filter. The filter should be able to process the whole water in the tank within a short period.
Water and Tank Conditions for Goldfish
You must meet the water and tank requirements of the goldfish. These requirements ensure the good health and wellbeing of the goldfish. Your goldfish might not thrive if you do not meet these conditions. Here are the water and tank requirements for the goldfish.
- pH: The pH of the water for your goldfish is not very critical, as the goldfish can thrive in several pH values. But, the ideal pH value for the goldfish should fall between 7.0 and 8.4. This pH shows that goldfish can thrive in neutral water as well as alkaline water. Goldfish do not do well in acidic water, but you shouldn’t worry about this because most water are alkaline; only a few turn out to be acidic. You can measure and keep track of the pH of your goldfish’s water using the litmus paper or a colorimeter.
- Temperature: Water temperature is also a very important factor to consider when keeping a goldfish. Goldfish are cold-water fish, but they can also thrive in warm water or heated environments. The ideal temperature for fancy goldfish ranges from 68°F to 74°F. Other species will do well in 600F to 700F. In case you cannot meet the temperature range, you should not be too far from it to ensure your fish’s wellbeing.
- Hardness: The hardness of the water for your goldfish should be moderate. Goldfish will thrive in water with slight hardness. They can also manage water that slightly exceed the hardness value.
- Tank size: The ideal tank size for an adult goldfish ranges from 10 gallons to 20 gallons depending on the species. The tank size for fancy goldfish is 10 gallons, while other species will go with 20 gallons.
Suitable Tank Mates for Angelfish
There are several suitable tank mates of the angelfish. The angelfish is a very peaceful fish, making it compatible with several fish and aquatic animal species. However, angelfish tend to be aggressive towards other cichlids, especially during mating seasons. Here are suitable tank mates for angelfish;
- Corydoras catfish: The corydoras catfish is the most suitable tank mate for angelfish. They have good schooling behaviors and are also very hardy, like angelfish.
- Bolivian rams: This fish is a close second suitable tank mate of the angelfish. They are very hardy, easy to keep, and are bottom dwellers. Their small size makes them compatible in the same tank as angelfish.
- German rams: This species of fish is more colorful than the Bolivian rams but fragile. They are slightly difficult to keep, but they are very suitable tank mates for angelfish if you are up to the task.
- Cherry barbs: These barbs are very good as tank mates. Unlike other barbs, like tiger fish that are not ideal tank mates, the cherry barbs are not prone to nipping when kept in groups. It is advisable to keep them in a group of six, and they become suitable for your angelfish.
Other compatible tank mates are; dwarf gouramis, Boeseman’s rainbow fish, zebra loaches, mollies, black skirt tetra etc.
Goldfish and angelfish are beautiful fishes that grace the tank. These two fishes are not compatible tank mates. Even though angelfish do not always do well with other cichlids, these cichlids are more preferable tank mates than goldfish.
