|Etymology||The name Ancistrus is derived from the Greek word agkistron, meaning hook, in reference to the interopercular odontodes that are hooked. This specific epithet literally means small frog or tadpole (ranunculus=diminutive frog or tadpole) and refers to its unusually wide head.|
- Shane's World Reproduction Breeding the Medusa Pleco, Ancistrus ranunculus
|Size||129mm or 5.1" SL. Find near, nearer or same sized spp.|
|Identification||Mature males and sometimes females have soft tentacles (bushy fleshy growths) on the snout - this is unique to the genus Ancistrus.
Although all black, this is an easily identified species of Ancistrus due to its extreme head-width.
|Sexing||Both sexes exhibit the Ancistrus trademark head-tentacles but they are much more prominent in sexually mature males.|
|Distribution||South America: Xingú and Tocantins River basins.

|Temperature||25.0-28.0°C or 77-82.4°F (Show species within this range)|
|Feeding||Although still omnivorous, tends to be more of a carnivore than your average Ancistrus.|
|Furniture||Natural habitat is stony streams. Prefers to hide between cracks in the rock-base or under flat stones on the bottom.|
|Compatibility||A good complement to most aquariums, they are not aggressive to other species. Males may fight over territory if kept in too small a tank.|
|Suggested Tankmates||All community fish, small to medium sized cichlids.|
|Breeding||Typical Ancistrus breeding behaviour. Males stay in caves and guard the brood. Females lay about 8 to 12 eggs. Eggs hatch after 5-7 days. After about 10 days the yolk sac is totally absorbed and the young start to eat. Fry are not problematic to raise. Once conditioned for spawning they spawn as often as common Ancistrus.
