Before you get your first aquarium and fish, you need to know everything about them in advance. Look for information on the Internet or from knowledgeable people. Here is a quick tip – do not rely on the seller, you will probably not learn anything specific.
Many people are mistaken that fish are just for aesthetics in the home and do not take into account a number of important things when buying them. This, of course, is completely wrong and usually leads to unpleasant experiences.
One of the biggest mistakes of novice aquarists is that they choose their aquarium fish according to their personal tastes and do not take into account the individual characteristics of each species. Compatibility is a very broad topic that cannot be discussed in a few sentences. It is necessary to study the individual requirements for each of the fish that we have selected and assess whether their natural habitats are similar.
A typical example of the incompatibility of aquarium fish is goldfish and angelfish. Goldfish love cold water and are virtually incompatible with any other species of aquarium fish. On the contrary, Angelfish like higher temperatures and can be combined with other species of aquarium fish.
In the following lines, we will discuss why Goldfish and Angelfish are incompatible in-depth. We will also discuss the suitable aquarium inmates for both species and how to select them without making mistakes.
Can Goldfish live with Angelfish?
We have mentioned the main issue with keeping Goldfish and Angelfish in the same aquarium – they thrive in completely different natural habitats. Goldfish need cool aquarium temperatures in order to be healthy and happy. On the other side of the spectrum, Angelfish require temperatures between 24 and 28 degrees. Exposing your Goldfish to high temperatures and your Angelfish to the opposite will only lead to serious health issues with the fish and a fatal end.
Besides the obvious temperature requirements, there are several other issues that should convince you against keeping Goldfish and Angelfish together. Angelfish are a very predatory species and become relatively large as they grow older. As predators, it is natural for them to attack the Goldfish and there is almost a 100% guarantee that it will happen eventually.
Depending on the species, Goldfish can also grow surprisingly large but this also means that they require a lot more space to thrive healthily. This fact also makes them incompatible with most other species.
Experts normally recommend at least 10 gallons of water per single Angelfish and this number increases as the fish grows. They can thrive with less space but if you want to provide the best living environment, you need to follow these requirements. If you have a pair of Angelfish, this means at least 20 gallons.
Goldfish, in turn, require even more space. For starters, you need at least 20 gallons to keep a single Goldfish happy and at least an additional 12 gallons if you want to keep a pair. And that is for a regular-sized one. A large Goldfish may require 50 gallons or more.
Surprised? Did you think that keeping a Goldfish in a bowl is the right thing to do? This practice was mainly popularized by movies but in reality, it is a devastating environment not only for Goldfish but generally any other species too. This is also the reason why most Goldfish in tight aquarium spaces do not grow at all. Fish growth depends on their living space and Goldfish can generally grow much larger than you are used to seeing.
Last but not least, Goldfish create a lot of waste that pollutes the aquarium. Angelfish are susceptible to sudden changes in the environment and can get uncomfortable easily. A polluted environment will only lead to health problems apart from the aforementioned behavioral issues.
What Fish Can Live with Goldfish?
As mentioned several times above, finding suitable tank mates for Goldfish is troublesome, if not unnecessary. Starting with their temperature requirements, most common aquarium fish are eliminated. You either need to find species that thrive in colder environments between 65° and 75°F (18°-24°C) or you can forget about it.
Next up, you must consider size. There is a simple rule for fish in aquariums. If one fish is small enough to be eaten by the other, chances are it will happen. Furthermore, Goldfish tend to eat a lot and by a lot, we mean that they are always hungry.
Choose fish that are at least their size unless you want to wake up with one or two missing fish in the tank. If you choose fish species that are smaller than the Goldfish, at least make sure that they can outswim the predator.
Other than that, Goldfish are generally peaceful which means that you really should not add aggressive species as tank mates. Angelfish are a good example and there is almost a 100% guarantee that they will bully the Goldfish.
Last but not least, it all depends on the species of Goldfish you have in your aquarium. There are over 200 species and each one has completely different characteristics and requirements. Some stay small while others can grow to abnormal sizes. Always research the selected species before you select tankmates. With this said, here are several fish you can generally keep with a Common Goldfish:
- Rosy Barbs
- Giant Danios
- Dojo Loach
- Hillstream Loach
What Fish Can Live with Angelfish?
Angelfish give you plenty of options when it comes to tank mates. Their requirements are not as unique as those of Goldfish.
It is good to know that Angelfish occupy the higher levels of the aquarium. If you want to keep them away from trouble, do not add other species that occupy this level. Choose some that prefer the middle or bottom of the tank.
Make sure to select species that thrive in similar warm tropical environments. They also prefer soft and acidic water environments which should be considered when selecting tank mates.
Once again, size matters. Angelfish grow surprisingly large despite their miniature size as juveniles. Like Goldfish, they will eat anything that is smaller and slower than them, so pick similar-sized species. Here are several great tank mates for Angelfish.
- Corydoras Catfish
- Dwarf Gourami
- Zebra Loaches
- Ram Cichlids
