 Cat-eLog Data Sheet | |
|---|---|
| Scientific Name | Ancistrus macrophthalmus (Pellegrin, 1912) |
| Common Names | LDA074, Large Eyed Bristlenose Storøjet Sugemalle (Denmark) |
| Type Locality | Río Orinoco, Venezuela. |
| Synonym(s) | Xenocara macrophthalma |
| Pronunciation | an SISS truss |
| 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 refers to its big(makros=big, large) eyes(opthalmus=eyes). |
| Species Information | |
| Size | 79mm or 3.1" 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. When first described, Pellegrin remarked that compared to other Ancistrus (known at the time), this species has relatively larger eyes, a wider head, fewer interopercular odontodes, and a flatter body profile. Body color is overall brown above, white below. |
| Sexing | Both sexes posses soft tentacles at adulthood. In the male they are typically thicker and often branched. |
| Habitat Information | |
| Distribution | South America: Orinoco River and lower parts of some of its tributaries in Venezuela. Orinoco (click on these areas to find other species found there) Login to view the map. |
| IUCN Red List Category | Least Concern , range map and more is available on the IUCN species page. Last assessed 2020. |
| Husbandry Information | |
| Feeding | Ancistrus should be fed mainly on vegetarian foods. Prepared foods include algae wafers and spirulina based sinking food. Vegetables such as courgette/zucchini, and (English) cucumber are an excellent addition to the diet, along with the odd, small amount of more meaty foods. User data. |
| 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 | Appropriate with most community fish that aren't overly big or aggressive. |
| Breeding | All Ancistrus species are cave-breeders, where the male looks after the eggs and young fry. |
