Can puffer fish live with parrot fish?

* Different water parameters: Pufferfish and parrotfish have different ideal water parameters, such as temperature, salinity, and pH. Maintaining optimal conditions for one could be detrimental to the other.

* Dietary needs: Pufferfish are primarily carnivorous, while parrotfish are herbivorous. This makes it difficult to provide a balanced diet for both species in the same tank.

* Territorial behavior: Both pufferfish and parrotfish can be territorial, especially the larger species. This can lead to aggression and fighting, particularly if the tank is small or if the fish are not properly acclimated.

* Toxicity: Some pufferfish species are highly toxic, and their toxins can harm other fish in the tank.

In conclusion: While it might seem appealing to have these colorful fish together, it's not recommended due to their different needs and potential for aggression.

If you are interested in keeping both pufferfish and parrotfish, it is best to house them in separate tanks.
