Description: Dorsal spines (total): 1; Dorsal soft rays (total): 6-7; Anal spines: 1; Anal soft rays: 4; Vertebrae: 28 - 29. Small, wide, and very depressed body; short dorsal fin (3.9-4.6 times in SL); wide mouth; a small area of supraoccipital plate often depressed, slightly granular or without odontodes; exposed part of nuchal plate minute or totally covered by skin; dorsal and fins brownish with numerous small whitish spots, lips and belly yellowish, totally or mostly unpigmented. Dermal plates along dorsal-fin base 7-8. Short interdorsal distance, 5.5-6 times in SL. Aquarium Care: The Ancistrus genera make good community fish where they do not grow too big for the aquarium. Some species have different requirements in the aquarium so best to read up on the species you have whereas if they need higher oxygen requirements or not, or if they prefer cooler waters if they originate from the southern parts of South America against the species from further up north. Diet: Vegetable foods such as cucumber and courgette and also tablet and meaty foods. Reproduction: The female lays her eggs in caves or crevices... that the male has chosen and cleaned.... as a cluster. The male usually then guards the eggs after ejecting the female. The fry then cling to the sides of the cave and when they use up their yolk sac, which is around the four to seven day period, they will be ready to feed on infusuria, vegetable matter, brine shrimp naupli or micro worms. In a community tank a few will survive if enough hiding places are afforded to them. Etymology: The specific name minutus: Minute, known for its small size. Remarks: This small species is sometimes exported alongside Ancistrus aguaboensis from the Rio Tocantins.
