Relevant Information:

The Blue Shrimp Catfish (Imparfinis mirini) hide under the rocks and roots during the day and around sunset they start preying on shrimps, insects and fish fry. They are very sensitive. Aquarium Care: Peaceful towards conspecifics but territorial with its own kind. Provide a moderate sized aquarium with hiding places such as bogwood, rockwork and plants. A good water flow is recommended with good aeration and filtration. Diet: Live, frozen and flake foods. Etymology: The specific name mirini: named for Rio Piracicaba-mirini, near Piracicaba, Brazil, type locality. Remarks: The second thumbnail image shows a specimen after capture with stress colouration, and after a few shots it recovered and fled into hiding under a big log (Petersen, P.).
