Scientific Name Hypancistrus sp. (L287)

Pronunciation hype an siss truss
Etymology A contraction of the Greek hypo (meaning less than) and ancistrus, an allusion to the reduced number of teeth (particularly in the lower jaw) found in this genus. 
Jump to next section Species Information
Size 120mm or 4.7" SL. Find near, nearer or same sized spp.
Identification L287 is not a usable L-number, in the sense that the original photograph shows a photo of a fish reported collected from the Rio do Para, but the photographed fish doesn't come from Rio do Para. So, it was either what is now either L399 or L400.
Sexing Mature males have thicker first pectoral ray, more pronounced odontodes on the first pectoral fin ray and odontodes on the rear of the body, and typically a wider head. Mature females are wider around the middle of the body, and much less noticeable body and fin odontodes.
General Remarks Unfortunately, there is much confusion surrounding this fish. DATZ issued it L 287 in December 2000. Then in Feb. 2001 DATZ issued L 287 to a Hypancistrus-type fish from the Rio Curua-Una, Para, Brazil. The second fish issued L 287 was later given the L Number L 307. DATZ listed L 287 as coming from the Rio do Para, Brazil and reaching 10cm. Das Aquarium issued the same fish the designation LDA 69, stated that it came from "Venezuela," and grew to 7cm. The 2nd Ed. Aqualog book (2004) then published that the fish was in fact not from the Rio do Para, but a tributary of the Rio Xingu.

Feeding Unlike the popular opinion of many other loricariids, Hypancistrus are more carnivores than algae eaters. This is backed up by a small and lightly toothed mouth that indicates they are poor algae scrapers. Provide small and frequent supply of mainly meaty foods such as dry discus food, bloodworm and even brineshrimp with the infrequent offering of flake or algae tablets.
Furniture Sand, primarily rocks and optionally driftwood. Caves made out of slate plates, bamboo or PVC pipe.
Compatibility Suitable with most fish, as long as they are not too large or territorial about bottom-space.
Suggested Tankmates Small tetras and other similar small fish. Also Corydoras. Care has to be taken to ensure that they get enough food, as they can be a bit shy and slow to grab food when available.
Breeding Unreported.
Breeding Reports There is but a single breeding report, read it here.
