The body length is about 50 cm, up to a maximum of 70 cm. A mature pinnatus batfish can reach an average size of over 30 cm in a breeder tank with a fin’s height of up to 46 cm.

The Appearance of Full Grown Pinnatus Batfish
Indifference, mature Pinnate batfish appear to be completely different from the juvenile batfish. The attractive, dramatic colors of the baby pinnatus batfish become dim when the fish matures and finally disappears abundantly.
Juveniles have a beautiful red border on their body and wings. However, this usually disappears as an adult. The body has straight brown and brown silver bands.
Adult pinnatus batfish looks like a triangular shape because of its long flowing fins. The fish’s rich black color gradually fades to a dark silver color.
Most mature pinnatus batfish have dark bands along with their eyes, and also, two other bands move along with the body of pinnate batfish.
What Do Pinnatus Batfish Eat?
Providing wild batfish with their nutritional needs was a problem for aquarists. In the past, most juveniles survived no more than a few weeks after adulthood, especially since their diet was insufficient for their needs.
It is challenging to feed the pinnatus batfish in the breeder tank, even for some trading enterprises. Small live shrimp is a popular food that complements their diet.
Captured wild pinnatus batfishes can grow by feeding them fish of fresh and saltwater. There is more chance for life if your fish learn to eat live food.
Batfish was considered carnivores for years. However, recent studies proved that these species also eat algae. You have to give food in small amounts to your pinnatus batfish many times a day.
Adult pinnatus batfish should be fed with scallops, live shrimp, mussels, and small live shrimp. To supply an appropriate amount of nutrition to them, seaweed and algae should comprise their diet.
Adult pinnatus batfish are very slow to take food. Due to this reason, they are mostly in hunger. That’s why to keep an eye on your pinnatus batfish to make sure it gets a full serving of its food.

Behavior & Habitat of Pinnatus Batfish
Pinnatus batfish is a calm, moderate-moving species that is very friendly to other fish that occur in their own species and come from identical environments.
These fish occur at depths of up to 20 meters. Pinnatus batfish are always searching for ledges and caves, these fishes travel along with reefs and always like shallow water.
Juveniles mainly swim alone in shallow seas and inhabit coral reefs or rocks. To avoid being preyed on by big fish, they often lie on their sides and move their fins in a wave shape to imitate poisonous flatworms to protect themselves.
Adults like to swim in groups on the outer edge of coral reefs, and they come out day and night. The personalities are very “approachable,” and it is easy to get close to divers.
Pinnatus Batfish Care
Pinnatus batfish are challenging to keep in the breeder tank and traditionally do not survive long after childhood. It is possible to grow one of these pinnate batfishes by keeping them properly and providing appropriate nutritional food.
Pinnatus Batfish Tank
In the wild, pinnate batfish can grow up to 2.5 feet, although you have to keep only small specimens in the breeder tank.
Therefore, the size of the tank could fit on it. Pinnatus batfish need a home breeder tank of at least 760 liters and preferably more. The dimension of tank height should also be deep enough to take one of the tall batfish.
Keep in mind that many fish diseases are caused by stress, and the wrong size of a tank with insufficient swimming space is a major cause of stress.
Pinnatus Batfish Tank Condition
Pinnatus batfish are not appropriate for open breeder tanks because they feed on invertebrates and corals. They hide under the rocks on the border of the reef.
But you can hold one of these ocean charmers by creating conditions similar to their natural habitat. To reproduce the natural environment of the fish, you need to use a sand substrate.
Pinnatus Batfish required enough free space in the breeder tank for swimming and some deep places where they can hide when in hazard. Caves, overhangs, and Live rock are ideal for this.
However, be careful not to turn the tank full of these things so that the swimming area is not blocked, and avoid adding rocks in bulk quantity as it may cause serious injury to your fish.
Pinnatus batfish are saltwater fish that need a saltwater environment, although they sometimes occur in brackish water.
Temperature & Water Condition
The water temperature should be between 25 °Celsius and 27 °Celsius. The potential hydrogen value should be in the middle of 8.2 and 8.4, an alkalinity value should be in the middle of 10, 12 dKH, and the SG is between 1.019 and 1.026.
You required a good filtration system consisting of mechanical, biological, and chemical equipment to keep the water clean.
If you want perfect tank conditions for the pinnatus batfish, you should have a container with a quality protein shaker and a dry/wet filter function. To minimize the risk of diseases at the tank, you can also use UV sterilizers that kill the parasites responsible for the disease.
