Can Bluegill and Goldfish Live Together in a pond?

Many pond owners enjoy keeping both bluegill and goldfish in their ponds. However, it is not always easy to determine whether or not these two species will be compatible with one another. In this blog post, we will explore the pros and cons of each fish as well as what you need to do if you are considering adding them to your own backyard pond.

Can these fish live together?

Many hobbyists use both bluegill and goldfish in the same pond. However, it is important to remember that these two species will be vying for a lot of the same resources. Your best bet, therefore, is to place mature fish in your pond and choose only one variety to keep there.

If you are hoping to add bluegill to your pond, you should also keep in mind that they are predators. This means that they will be looking for a food source and if your goldfish population is not well established, it may become an easy target.

While bluegills do get along with other species such as perch, and crappie, they will also try and feed on your small fish. So, it is important to remember that these two species may not get along well with others. If you are adding bluegills to a pond full of small fish, you will need to take extra precautions for the sake of the other inhabitants.

Compatibility

In order for both species to coexist well, it is important to remember that bluegills are much smaller than goldfish. This means that their population will naturally be larger and they will require more food for sustenance.

Because of this fact, you will need to provide your fish with an ample supply of pellets as well as a healthy amount of live insects. You should also add a small amount of liquid fish food to your pond so that the goldfish can have access to it as well. If there are not enough pellets for both fish, they may become aggressive towards one another.

In addition to providing a proper supply of food, you will also need to be sure that your bluegills have adequate cover in which to hide. If they are not provided with this, your goldfish may be able to eat all of the bluegills if they decide to attack them.

When choosing which species you want for your pond, it is important to note that both will need at least a 50-gallon fish tank each in order to thrive well. Though your goldfish may not be in the same tank as your bluegills, you will still want to make sure that they have a lot of space with adequate cover.

If you are concerned about the compatibility between these two species in your pond, it is best to consult with a professional before putting them together. They can help you plan out how you will care for each species as well as how many bluegills you will need to keep in order to achieve the best results.

Do bluegill eat goldfish food?

Yes. They will eat goldfish food and even baby fish, which is why it is important to have a good ratio of bluegill to goldfish.

Some bluegills are more aggressive than others, so the aggressiveness factor also needs to be considered when stocking your pond with these two types of fish together (bluegill and goldfish).

What kinds of fish live with bluegill?

Koi

Koi are hardy fish that you can try with bluegill. Koi eat a variety of foods including snails, insects, and fruit.

Koi are also heavy and may be difficult for smaller bluegill to eat.

It is important to know if you have koi in your pond that they can grow very large (up to 3 feet long).

Catfish

Bluegill are not likely to be able to eat your catfish. Catfish, in general, are heavier and can easily defend themselves from bluegill predation.

Catfish do better in large ponds where they have plenty of places to hide from bluegill, and usually prefer live food.  That said, catfish will eat a variety of foods including snails, insects, and plants.

Crayfish

Crayfish are a great alternative to fish in your bluegill’s pond. Crayfish can grow large, but they are also more likely to avoid predators than many other pond animals.  Crayfish like snails and plants as well, making them a good addition to your garden.

Crayfish do not compete with bluegill for food, but they do compete with bluegill for habitat.  Make sure you have plenty of room if you want both of these animals in the same pond.

Black crappie

Black crappie can be a good addition to your bluegill pond as well.  They are not likely to cause trouble for bluegill and you may even find the fish swimming together.

Crappie will eat snails, insects, and plants, though they prefer larger insects and crustaceans if available.

You may be able to feed your crappie scraps like bluegill.

Bluegill and goldfish tank requirements

Tank size – 80 gallons is the absolute minimum for a bluegill and goldfish mix, but 80 to 120 gallons is better.

Water temperature – between 68 and 72º F (20 to 22° C)

Water chemistry – rather soft, pH 6.5 to 7.0, and low carbonate hardness (under 10)

Food – quality bluegill food or goldfish flakes plus frozen bloodworms and brine shrimp

Do not stock your bluegill and goldfish tank with too many fish. It’s best to start out with 1 inch (2.5 cm) bluegill and 1-inch goldfish, keeping a 1:1 ratio of fish to tank volume. Many aquarists report success with adding 2-3 additional inches (5-7.5 cm) goldfish in the second year of the mix.

Two bluegills should be compatible with one adult goldfish. If you want to keep more bluegill or goldfish, add them in pairs.
