Description
editP. joselimaianus has a dorsoventrally flattened body, dark brown in colour with light "gold" spots covering the whole body and fins. It has a large dorsal fin with 10 rays, characteristic for the Pterygoplichthys genus. On all fins the first ray is thicker, and on the pectoral fins there are visible spikes. It's a large fish, growing to a length of around 30.5 centimetres (12.0 in) SL.[4]
These fish prefer temperatures ranging between 26 and 29 degrees Celcius, and pH between 6.5 and 7.5.
Etymology
editThe fish is named in honor of ichthyologist José Lima de Figueiredo (b. 1943), of the Museu de Zoologia da Universidade de São Paulo, because of his support and observations on the species covered in the author's paper.[5]
