The red parrotfish can be kept in a mixed aquarium with a variety of ornamental fish, but attention should be paid to their habits and territorial awareness.

The red parrotfish has a gentle temperament and is suitable for being mixed with some fish that are also gentle and don't have a strong territorial sense. For example, the flowerhorn cichlid needs to be raised with the parrotfish from a young age, because it's very difficult to keep them together when they grow up, as the flowerhorn cichlid has a relatively strong territorial awareness. The Oscar fish has a gentle personality and isn't fussy about food, so it's suitable for being mixed with the parrotfish. The silver arowana and the parrotfish swim in the middle and bottom layers respectively, and mixing them can make the fish tank more lively. Fishes like theosphronemus goramy and the golden arowana are also suitable for being mixed with the parrotfish, because their colors and body shapes create a beautiful visual effect with the parrotfish.
When mixing different fish species, the following points should be noted:
Territorial Awareness: Choose fish with weak territorial awareness to be mixed with the parrotfish.
Size Difference: Make sure that the fish to be mixed have similar body sizes to avoid the big fish bullying the small ones.
Food Habits: Select fish that aren't fussy about food or have different food habits to avoid competition.
By reasonably choosing the fish for mixed breeding and paying attention to these details, a harmonious coexistence of the fish in the fish tank can be ensured.
