Product description & details
Otocinclus cf. macrospilus, also known as Dwarf Sucker or Dwarf Otocinclus, is a freshwater fish native to South America that belongs to the family of suckermouth catfish. Its distribution area is various river sections of the Amazon in Peru, Colombia and Ecuador. It is an enjoyable algae eater that lives in loose associations with numerous conspecifics.
Care in the aquarium
In the aquarium, this catfish feels most comfortable in the company of other fish of its own kind. An aquarium volume of at least 60 liters (better 80 liters) and a group size of 6 animals or more are therefore among the minimum requirements for the approximately 3.5cm large fish. The aquarium is optimally set up with fine substrate (sand), dense edge plants and roots. Other hiding places include stone structures and caves/tubes. When caring for the small catfish, care should be taken to ensure that the water is clean and rich in oxygen. As an extremely peaceful fish, the Dwarf Sucker can easily be socialized with other peaceful fish. Since the small catfish feeds primarily on growth in the form of organic and algae films, it should only be placed in aquariums that have been running for at least 3-6 months and are therefore well established.
Feeding
As with all representatives of the genus Otocinclus, the food base of the Dwarf Sucker is formed by algae growth and biofilm. This need should definitely be taken into account so that the catfish stays healthy. Algae powder such as spirulina or chlorella as well as suitable tablet or granulate food and occasionally live or frozen food can be offered in addition.
Sexual characteristics and breeding
Differentiation between the sexes is relatively difficult in Otocinclus cf. macrospilus. Females are usually slightly larger and fuller than their male counterparts. Breeding in an aquarium is difficult and rarely successful. The eggs are laid by the female between stones and roots and fertilized there by the male. After about 3-4 days the young fish hatch, which after a few more days swim freely and feed on biofilm.
