The Paraguay Dwarf Sucker
(Otocinclus bororo) is common in Rio Formoso.
They are shoaling but sometimes I found only 2-3 together
and other times they were more than 40 individuals
in a group. For their diet they seem to eat detritus
of rocks, roots and branches. They grow to a mazimum
total length of 5cm. (Petersen, P.). Aquarium
Care: This is a small group of Loricariids
which do well in aquariaand will keep the
algae down without harming the plants in the tank.Best to keep in a group with more males for breeding
purposes. Reproduction: the females
will lay eggs on the plants and tank glass after the
females have been chased around the tank by the male.
Like Corydoras they present a t-position
breeding mode. Diet:Omnivore:
algae, tablet foods, flake and small frozen foods.
