Why Do Rainbowfish Cannot Live With Shrimp?

They are peaceful fish that are found in community aquariums. These fish are not difficult to care for, but they do require regular water changes and a varied diet.

Basically they are not true herbivores, but they do eat small invertebrates and meat as part of their diet. Here are few reasons why they can’t live with shrimp.

Omnivorous fish

These fish are omnivorous and enjoy a wide variety of food items.

They can be found in freshwater habitats, where they eat insects, small crustaceans, and zooplankton.

So it’s important to find a diet that will fit their preferences. One option is to feed these fish high-quality flakes or pellets.

These foods are both high in protein and provide them with all the nutrients they need.

They can be a threat to your aquarium shrimp. When they’re small, they eat small shrimp, but when they get bigger, they’ll eat any fish in the aquarium.

Create anxiety

Rainbowfish and shrimp are two of the quickest-moving creatures in the tank.

Second, they can swim close to the shrimp, which can cause them to feel crowded and stressed.

Territorial behavior

Rainbowfish become territorial during the breeding season. If a shrimp is in the area where the rainbowfish is defending its territory, there is a good chance of a confrontation.

The shrimp may be eaten, or injured if it is not kept carefully.

Besides, female rainbowfish hide their eggs in vegetation. On the other side, shrimp shelter them from predators when they have dense vegetation too.

So it should come as no surprise that they are often in conflict with one another.

Unfortunately, this often means that the two species will confront each other during the breeding season.

Eat anything

Shrimp are opportunistic eaters capable of ingesting anything that they can get into their mouths.

Any edible food, including fish eggs, is acceptable for them. Shrimp aren’t whatever you think about as being suitable for a breeding tank.

Often, fish owners have reported cases where some shrimp species ate fish fry. Thus, shrimp aren’t a suitable fish for a breeding tank in that circumstance.
