|Cat-eLog Data Sheet|
|Scientific Name||Panaqolus nocturnus (Schaefer & Stewart, 1993)|
|Type Locality||Río Santiago near la Poza, Río Marañón basin, 4°01'24''S, 77°45'06''W, Depart. Amazonas, Peru.|
|Pronunciation||pan ack oh luss - nock-turn-us|
|Etymology||Panaqolus: Inelegantly derived from the indigenous term Panaque and in a form that infers a smaller size than that genus. The specific epitheht nocturnus is referring to night, presumably because the fish is mainly nocturnal.|
|Size||139mm or 5.5" SL. Find near, nearer or same sized spp.|
|Sexing||Like all members of the genus, males grow elongated interopercular odontodes during the breeding season. Males develop noticeable odontodes along the dorsum (back of the body) as well. Males develop small pointed genital papillae, whereas mature females will have large, rounded, swollen papillae. Additionally, gravid females have noticeably wider bodies between the pectoral and pelvic fins when viewed from above, compared to males.|

|Feeding||This genus feeds on wood, and should have several pieces, preferably several kinds of wood to chew on. Aside from wood, a mainly vegetarian diet is recommended, prepared food such as algae wafers and fresh vegetables, such as courgette (zucchini) and tubers such as potato or sweet potato (yams).|
|Furniture||Rock piles are optional and wood tangles are a must. Plants are not vital and will be nibbled or destroyed.|
|Suggested Tankmates||Works well with most types of peaceful community fish. Can be somewhat territorial towards conspecifics, but given enough hiding spaces, a group can be kept in a suitable size aquarium - roughly requiring a 30 x 30cm area per fish.|
|Breeding Reports||There is no breeding report.|
