All About the Mitratus Butterflyfish

In this article, we'll be learning all about the Mitratus Butterflyfish. This fish does well in various aquariums and is a fairly hardy fish, and adapts well to aquarium settings.

Prices: Ranges from $300-$400.

Tank Size: For Butterflyfish, they can get pretty significant. So by adulthood, they would need about a 100-gallon tank to give them plenty of room to swim around. This also gives them tons of rocks to be grazing upon. 

There will be plenty of liverock on a typical tank setup, so you add that in your tank and build caves, overhanging, and dark spots for this fish to hide and relax as they acclimate to the tank. 

Care Level: Moderate. Acclimation of them and their diet is the key to taking care of the fish can be more difficult wherever you have one in the tank. 

Temperament: They are peaceful fish and can even be in pairs, like most other fishes. You don't want to put them in the aggressive fish tank as they will not adjust to it quickly. 

Reef Compatibility: This fish is not reef compatible because they'll constantly pick on polyp corals.

Origin: They come deep underwater in the Maldives and around the island.

Water Parameter

  • Temperature: 72-78
  • dKH: 8-12
  • Salinity: 1.020-1.025
  • pH: 8.1-8.4

You don't want any spikes to happen, especially when they are first introduced, keep up with your water changes, watch the ammonia and nitrates, and you'll be fine taking care of this guy.


Maximum Size: These fishes will be around 6 inches after hitting adulthood. So a decent-sized fish by the end. 

Colors: A very bright yellow body with 2-3 dominant black stripes across them. They look perfect under some LED lights.


Please provide them with various food, especially at the beginning. They can be wrong about not eating; just be patient, and try other things at different times of the day. Maybe turn your current off to let the food flow down to them.

Mysis, brine, krill, bloodworm, and turkey baster are great choices.

Plus, hair and natural algae growing in the tank is another great way for these to eat as they learn to eat from your eventually. 


They do great alone or just in a pair together. They aren't seen in groups. They also do well with other species of Butterflyfish. 

Put them in the docile fish-only tank - Tangs, Angels, Gobies, Clownfish, Brass, Blennies - it will get along with those just fine.
