The 15 Best Roseline Shark Tank Mates are fish that can handle the same things in terms of space and temperature, but also mesh well with the Roseline Shark in terms of temperament. These should be medium in size so as not to become prey, and peaceful such as Betta fish, Gouramis, and even some species of catfish. 

Roseline Shark Tank Mates – What You Need to Know

Find out everything you need to know about this fish and it’s neighbors!

Temperament

The temperament of a roseline shark is quite peaceful. They are gentle and like to be in a community, being very sociable. That being said, a roseline shark will not do well with fish that are aggressive, or fish that take up too much of their personal space. Plan your tank mates accordingly!

Size

The roseline shark is capable of growing around four to five inches long. This is not especially big, around medium-sized for most aquarium fish. However, this fish will eat fish that are tiny enough, so make sure to pick tank mates that are similar in size!

Competition

 Roseline sharks eat an omnivorous diet. They like seaweed and insects in their natural habitat, but will be just as happy with a mixture of flakes, pellets, and frozen foods from you.

Just be sure that any tank mates either have a separate diet or are deferential enough to avoid hogging all of the Roseline Shark’s food at mealtime!

Parameters ; Tank Setup

 A roseline shark needs at least 55 gallons in terms of tank size, and more is preferrable, especially when it needs to spend time in close quarters with other fish that are large enough to avoid being eaten. Remember to clean the tank often; Roseline sharks are susceptible to disease from cloudy water. 

Aim for a temperature of water between 60 and 77 Fahrenheit for the best results, and get other fish that enjoy the same.
