"Otocinclus species, the "Tiger" Otocinclus. An example of occasional offerings. These ones being spawned in good numbers in the orient for the pet-fish interest. Images shot at the 2001 Aquarama Show in Singapore. "
Reproduction, Sexual Differentiation:
Sexing otos is not difficult, but takes a trained eye. Due to their small size, the definitive gill cover spines and pointed genital papilla of males is hard to make out. Instead look to the females; they are decidedly broader and rounder in appearance.
Due to mixed species shipments, the wannabe breeder is encouraged to purchase and stock Otocinclus in as large a grouping as practical, and provide propitious circumstances (food, habitat, water quality) for nature to take its course.
Otos are are listed by some authors as "egg scatterers" contrasting with other egg-laying loricariid genera. I side with Speice, 1987, Emmens and Axelrod, 1978, Sands, 1988 list them as breeders of adhesive eggs on rocks, glass aquarium surfaces, and broad leaved plants respectively. Baensch and Riehl in their Atlases state that pairs do a "dance", embrace and about 50 transparent to cream to yellowish green eggs are laid in an upper corner of their tank. Young hatch out in 2-4 days... they list baby brine and spinach as first foods.
