Its diet is thought to actually consist mainly of aquatic arthropods.[1] The species may be nocturnal.[1] The karyotype has been reported to have 2n = 92,[2] but this number apparently actually came from a specimen of Ichthyomys pittieri.[3] A. leander is known from the Andes of northern Ecuador and Colombia at elevations of {{convert|2860|–|4000|m|abbr=on}} above sea level. This poorly known and rare species occurs along swift, cold streams bordered by subalpine rainforest or grassy paramo. It occupies a severely fragmented area of about 40 km2. Habitat loss and water pollution are major threats.[1]References1. ^1 2 3 {{cite iucn | author = Tirira, D.
