Pterosturiosoma microps



Pterosturiosoma microps are rarely seen in aquarists' collections, which is due to the small supply of these fish from Peru. Although the fish have an unassuming black-grey colouration, they still have an attractive appearance due to their impressive fins.

The fish are difficult to keep and should only be recommended to experienced aquarists. The biggest problem many aquarists encounter immediately after acquiring Pterosturios microps is that they are very difficult to get used to replacement food and will not eat anything in the aquarium for the first time.

Pterosturiosoma microps

The sex of Pterosturiosoma microps can be distinguished by the width of the trapezoidal area framed by the four bony plates in the genital area, which is wide in females and elongated and narrower in males.

As noted above, the main problem with these fish arises immediately after acquisition until they have recovered from the stress of transportation and become accustomed to aquarium conditions. During this time, they should preferably be kept in an aquarium without a substrate. Acclimatization of the fish can sometimes take 3 to 4 months. Once the fish begin to feed, they can be moved to an aquarium with dark sandy soil and large rocks at the bottom. Plant long-leaf shrubs, e.g. Vallisneria gigantea, at various points in the aquarium.

Initially, when the size of Pterosturiosoma microps not exceed 10 cm, they can be kept as individuals or groups of 3-4 fish in a tank of about 100 liters, but once the fish reach a size of about 15 cm, the minimum size aquarium for them to be 250 liters. It is possible to keep these fish in a common tank with other peaceful, not too active fish, which will not compete with Pterostriosoma microps for food.

Water parameters: temperature 24-28° C, Need filtration, aeration and a weekly change of ¼ of the aquarium water with fresh. It is desirable to create a small current of water in the aquarium.

Lighting is weak, lasting about 10 hours per day.

The menu of fish in the aquarium consists of mussels, shrimp, bloodworms, proboscis and dry flakes and pelleted foods, although it is desirable not to abuse dry food. Feed the fish in the evening once a day.

Reproduction

Under aquarium conditions Pterosturiosoma microps do not breed. All fish are supplied to the domestic market from their natural habitat.

The lifespan of Pterosturiosoma microps in aquariums is very short, about 1 year. Why this is the case is not fully understood.
