How to choose tank mates for guppies?

guppies image with text How to choose tank mates for guppies?

Choosing tank mates for your guppies is not rocket science but there are a few things that you need to keep in mind while choosing tank mates for your guppies.

1. The fish should require similar water conditions as guppies

When you want to keep other fish with your guppies you will need to make sure that the other fish requires similar water conditions i.e. water temperature, water pH, and water hardness as your guppies need.

This is important because every fish has specific water conditions requirements. And if you don’t provide them with the ideal water conditions then it’s not good for their health, proper growth, and development.

Here’s a table showing the ideal water parameters for guppies

AVERAGE LIFESPAN2-4 years
DIETOmnivore
WATER TEMPERATURE64–82° F
WATER pH5.5–8.0
WATER HARDNESS10–30
MINIMUM TANK CAPACITY5 gallons
BREEDINGLivebearers

2. You should choose peaceful fish for your guppies

Guppies are small peaceful fish. Guppies don’t bother any other fish.

But other aggressive fish can attack guppies and this can stress guppies.

If guppies are stressed continuously then this can lead to diseases and it can even lead to the death of the fish.

That’s why while choosing tank mates for guppies make sure that the other fish have a peaceful temperament and is not known for aggressive behavior.

3. Choose smaller freshwater fish

Guppies are small freshwater fish. So while choosing tank mates for guppies make sure that the other fish is not too big that guppies can fit into their mouth.

Because if guppies can fish into any other fish’s mouth then they can intentionally or accidentally eat guppies.

4. Avoid keeping fin nipper fish with your guppies

One of the reasons we love puppies is because of their beautiful big fins.

These attractive guppy fins also attract other fin nipper fish.

Fin nipper fish can tear the fins of guppies which can lead to bacterial infection in guppies.

The bacterial infection can even cause the death of the guppies.

So while choosing tankmates for your guppies make sure that the other fish is known for nipping on other fish’s fins.
