We all love the idea of a tank containing multiple species of colorful fish.
In this regard, it’s no surprise hobbyists want to put angelfish and goldfish together. These beautiful creatures are easy to care for and very eye-catching.
However, before combining two or more kinds of fish, we need to know if they would benefit each other or have the same tank requirements.
So can goldfish live with angelfish? No, they shouldn’t be housed together. They differ in fundamental regions, hence differing in living environments and personalities.
In this article, GA Pet Sitters will tell you the reasons keeping goldfish and angelfish is a bad idea. Shall we start?
Can Goldfish Live With Angelfish?
We know it’s tempting to combine goldfish and angelfish in an aquaponics fish tank. But remember, although they’re in the same kingdom, these two can’t live together.
At a glance, they may seem to be compatible since both are freshwater species. However, keeping them together is never a great idea, and the reasons are noticeable if you learn about them.
Why Can’t They Live Together?
As mentioned, every kind of fish has specific living conditions and tank requirements to thrive. Interestingly enough, their temperaments also vary, which may sound new to many beginners.
When combining two creatures, it could be a regretful choice if you have no idea how they live and grow.
Goldfish and angelfish are not supposed to be tank mates because of differences in aquarium temperature, aquarium pH level, tank size, diet, waste production, and personalities.
In a nutshell, goldfish are coldwater swimmers, by nature, thriving in fairly lower temperatures, whereas angelfish originate from a high-temperature amazon.
While goldfish grow well in the water of 62-72 degrees F, the tropical angelfish require water temperatures over 75 degrees F.
Indeed, non-fancy goldfish, like single-tailed, can live in the tropics where water temperatures are nearly 80 degrees. If we acclimate them properly, these hardy fish will be able to survive in a high-temperature range.
But most keepers like to raise fancy varieties, whose tolerance for high temperatures is extremely low. We can’t put them in improper water temperatures because our fish would stop eating, become ill, aggressive, or die.
So you see the first sufficient reason for keeping goldfish and angelfish separate now.
Goldfish require more space than their friends. While they generally need 5-10 gallons of water per fish, angelfish only demand around four gallons.
Goldfish grow to very large size of 12 inches or more in length, whereas angelfish’s average length can reach at most 10 inches. Adult goldfish may require 20-30 gallons of water per fish.
Please note, it’s advisable to keep your fish in a tank that accommodates 2-3 times their body width.
In fact, providing your ‘swimmers’ with an adequate-sized aquarium will help constrain their aggression as it reduces stress. If you put goldfish into small enclosures together with angelfish, the narrow space can limit their growth and cause hazardous health problems.
Besides, each kind needs plentiful space to grow and roam. Housing them together might quickly result in overcrowding.
Most freshwater species have a similar diet. Both fish are omnivores, preferring bloodworms, mosquito larvae, and brine shrimp.
Although you can feed them a variety of the same food, angelfish consume more protein, and goldfish require more ‘green’ food.
Chopped vegetables, like collards or mustard greens, are to both fish’s liking, but you need to feed them to goldfish in a higher quantity as these swimmers are still part of herbivorous species.
Goldfish also consume certain fruits, like orange slices, skinned grapes, or watermelon slices.
The lack of proper portions of food may cause your fish to incur malnutrition. They’ll become prone to illness and infection.
Aquarium pH Level
Aquarium pH levels have a vital role to play in your fish’s healthy development. The pH level of the water affects the metabolism and ability to take in water of your fish.
An improper pH level can pose detriments to their health.
Unfortunately, angelfish and goldfish don’t bear a resemblance when it comes to preferred pH levels. While angelfish can excel in the water of 6.5-7.1 pH (with 6.8 being the ideal level to promote breeding), goldfish thrive in the water of 7.2-7.6 pH.
Despite the ability to withstand some variations, goldfish are relatively sensitive regarding the pH level of the aquarium’s water. They can’t tolerate any fierce pH change.
On the contrary, angelfish are tougher and can adapt to a broader range of water’s pH levels. They’re fond of softer and mildly acidic water.
Expert keepers always pay full attention to maintaining a clean aquarium as it significantly impacts their fish’s health.
A tank with dirty water contains a very high level of ammonia. It may cause the fish to turn on, change their behaviors, and bite each other.
Apart from the pH, goldfish and angelfish also demand other different properties of water, including cleanliness.
In this regard, goldfish produce too much waste to live together with angelfish, whose sensitivity in cleanliness is very high. This difference can result in irritability and stress in the lives of fish, badly affecting their development.
Because of more waste production, goldfish also require more regular tank maintenance and a good filtration system to grow healthily. Meanwhile, their friends produce less waste and are low-maintenance.
That’s another reason to keep these two separate.
On top of the environmental and health aspects, when combining various species into an aquarium, their personalities and interactions with each other speak volumes as well.
Most fish remain the same temperaments throughout one species. Thus, it’s extremely crucial to make sure your fish are compatible with the other species. This way, you can deter them from being overly hostile.
Goldfish are non-aggressive breeds, peacefully interacting with other creatures. They’re not even scared of their keepers.
They only have a slightly hostile attitude toward a newcomer coming into their tank. Apart from that, goldfish are one of the noblest kinds of fish.
This creature can live pleasantly in a large group, showing warm and social behavior.
However, they won’t maintain this calm nature and will fight back when living with aggressive fish, like angelfish.
Angelfish are only easy-going when they’re young. Once they grow mature and older, they suddenly become aggressive towards other species in the tank.
It’s always better to let them live with the same kind. Even then, they still tend to be territorial.
Angelfish are particularly hostile in small spaces and breeding seasons. Due to the predatory nature, they will seek nutrients around them if you don’t provide proper feeding.
This issue also rises when they’re not in a favorable environment, especially at low temperatures.
In short, angelfish and goldfish have totally contradicting temperaments. While goldfish don’t pose any threat, angelfish can harm goldfish’s lives.
So, if you want to protect your precious creatures, never keep these two together.
Will Angelfish Kill Goldfish?
For some reasons relating to living conditions, angelfish get aggressive sometimes. However, angelfish rarely kill goldfish.
They may nip at times, but they would generally do well in a community aquarium.
Angelfish usually eat smaller swimmers, like neon tetras. If your goldfish’s size is smaller or similar, you’d better remove them right away from the tank.
After all, angelfish are predators. For such a peace-loving and slow goldfish, the angels will be a detriment. They will nip and sharply bite the gold.
Before buying new fish, you should check if they’re compatible with your existing one by asking the pet store. You don’t want to see your fish eventually hurt each other, do you?
What Kind Of Fish Can They Live With?
Again, goldfish are coldwater creatures. So it would be best if you look for fish in the same category or can withstand lower temperatures to be goldfish’s tank mates.
You should avoid certain carnivores to deter them from eating your goldfish, such as pufferfish, piranhas, oscar, arowanas, larger carnivores, and, of course, angelfish.
Meanwhile, angelfish eat smaller fish when breeding. Thus, we recommend you avoid any small-sized species that can fit into angelfish’s mouths.
We can name some ideal tank mates for angelfish, like adult platies, bettas, mollies, dwarf gouramis, plecos, swordtails, and ram cichlids.
Can goldfish live with angelfish? It should appear like a bad idea to you now.
An aquaponics tank full of beautiful creatures and species is always appealing to any fish enthusiast. Nevertheless, you have to research well before putting two or more kinds of fish together.
A perfect tank not only contains plenty of fish but also a peaceful and healthy living environment for your lovely swimmers. Once you learn about combining fish, you learn to become a good fish keeper.
We hope you have a healthy and magnificent aquarium for the best hobby enjoyment!
