I collected this fish on the rio negro and brought it back for my aquariums, i was only able to catch one.
Size: I have caught beautiful 8 inchers with hook and line.
Range: Rio negro basin, i have caught these fish in several differant places, in front of Manaus or a few days upriver.
Agression, tankmates: I have kept these fish with almost any small south american cichlid, catfish or characid. Very peacefull.
Housing requirements: An aquarium of at least 6 feet is needed when adult. Needs soft and acidic water, can be kept with plants and REQUIRES fine gravel or sand. Enjoys being kept in a group of three or more.
Notes: This fish does not mouth sand nearly as much as most geophagus species do. May uproot plants.
