How to Keep Guppies with Goldfish

In spite of this, there are still quite a number of differences between these two species.

Habitat

Guppies are tropical fishes, which means that they can survive in temperatures up to 86 degrees Fahrenheit.

On the other hand, goldfishes are cold water fishesOpens in a new tab., and any temperature above 68-74 degrees Fahrenheit would reduce the oxygen content of the tank, thereby stressing them, and in some cases resulting in physical deformities, or even premature death. Also, the guppies can be stressed by low temperatures as well.

Size Variations

One of the other names for guppies is Million Fishes, and this is because they breed and spawn at a very fast rate, this might result in overcrowding of your tank.

Apart from this, the goldfish grows upOpens in a new tab. to 10 inches and is an omnivorous fish, meaning that it enjoys both plants and animals as food. The average length of guppies is about 2 inches. Your goldfish might start to see your Guppy as a snack to nibble on after a while if they are kept together in the same tank as guppies.

Ph Differences

The goldfish is an acidic dish that thrives best in ph ranging from?? to??; whereas, the guppy is an alkaline fish that thrives under a ph ranging from 6.8 to 7.8.

The goldfish is known to produce a high quantity of bioload that might even make the water more acidic for your guppies, thereby stressing them.

How do you ensure that they live together

Set the temperature to a common value

You should aim for a temperature of 70 degrees Fahrenheit in your tank if you would be keeping your goldfish together with guppies. This makes your tank cool enough for your goldfish and warm enough for your guppies. However, keep in mind that this is not the optimum temperature required for them to thrive, it will only help them survive.

Constantly Monitor the Ph of your Tank

You have to make sure that the ph in your tank is at least neutral, at a ph that is not higher than 7. This is the midpoint that would be suitable for both your guppies and goldfish. It is advisable to check for the ph in your tank first thing in the morning, or at night because there are mild fluctuations in PhOpens in a new tab. values during the day.

Size of tank

On its own, the goldfish requires a tank of at least 20 gallons; with the inclusion of the goldfish, the adequate tank size might increase up to 25 or 30 gallons because the guppies breed very easily, and you would not want them to overload your tank.

Filter

It is recommended that you get a filter for your tank and routinely filter because the goldfish are heavy producers of bioload, routine filtration would help to reduce this bioload that might otherwise affect the health of your guppies.

Frequent Water Changes

It would be helpful if you change at least 30% of the water in your tank every 2 weeks, this is also to reduce the quantity of bioload produced by the goldfish in your tank.

Routine water changes would help to improve the quality of the water in your tank. Although, you have to be careful when doing this because you might end up filtering more than the required quantity and this would result in an upset in the chemical balance of your tank. So make sure that you do not exceed the stated 30%, every 2 weeks.

Can guppies live alone?

Although it is possible for guppies to survive individually, it is not so healthy for you to keep your guppies alone in a tank, because in their natural habitat, guppies are seen swimming in groups and have been found to thrive better when kept with other similar fishes.

You have to make sure that you do not keep too many guppies of the opposite sex in a tank because guppies breed quickly and easily and you would not want to overcrowd your tank. If this happens, you have to increase the size of your tank.

Can guppies live in pairs?

Yes, guppies can live in pairs. They have been found to flourish if they are kept together in groups. They are very active fishes that enjoy swimming in the same environment as other fishes of the same species or temperament.
