Freshwater Fish from Uruguay 2nd. edition (1) Sarmento-Soares, L. M., & Martins-Pinheiro, R. F (2)

Description: Dorsal spines (total): 1; Dorsal soft rays (total): 4-5; Anal soft rays: 9 - 12; Vertebrae: 34. The unique colour pattern of dorsum and dorsolateral sides greyish-brown with small dark chromatophores, becoming sparse and faint towards the ventral portion of the body, distinguishes this species from all congeners. Can be further diagnosed by the following combination of features: nasal ossified with wide medial flanges partially sutured to lateral border of mesethmoid; 4 branched rays on pectoral fin; ribs attached to consecutive post-Weberian vertebrae; with two vertebrae alternatingly unribbed and ribbed; first nuchal plate somewhat elliptical to rounded; eye 17.4-22.8% HL; caudal-fin lobes of equal length in mature females, upper lobe slightly elongated in mature males; and vertebrae 34. Habitat: Found in rivers with bedrock and loose stones on the bottom. Aquarium Care: Give them small pipes, as they do seem to like to hide in the crevices of bogwood as well. They appear to be happier if they can jam themselves in with the use of their pectoral fins. Community tanks are fine for this species although you may find that they will predate on fry from other species, but apart from that they come well recommended but don't expect to see them too often. Diet: In its native habitat they feed on small invertebrates and crustaceans and in the aquarium they will eat anything given such as frozen bloodworm inserted in to their hideaway, catfish tablets, white worm (sparingly) and prawns and shrimp. They do like their food and you can see them shooting out of their hideouts and swimming in a frenzied manner to try and take all for themselves, especially when you feed them their favourite food, frozen bloodworm. Another food that they love is Fish Farm pellets but you have to watch the water quality with this food as it can quickly foul the water, so feed sparingly. Etymology: Bohemian, i.e., “one who lives unconventionally, chiefly at night,” referring to its nocturnal habits.
