The interopercular odontons are also longer in the males.

Water values for Belo Monte Loricariid L399

  • GH 3 to 15
  • KH 0 to 7
  • Temperature 26 to 30°C

Food and feed for Belo Monte Loricariid L399

The ideal aquarium for Belo Monte Loricariid L399

A tank size from 200 l upwards is advantageous, because the fish with a final size of up to 13 cm needs a lot of space. Especially if it is kept in small groups. The Belo Monte Loricariid L399 is a twilight or nocturnal fish, therefore the aquarium should not be too bright. For the well-being of the catfish also caves and/or stone crevices contribute, into which the quite shy animals can retreat. Plants in the aquarium are of less importance, especially since younger specimens of the species like to nibble on them. Especially succulent stem plants do not survive for long. If plants do, then preferably hard-leaved, bitter tasting species such as Anubias or Java fern. As with all catfish species, the substrate should consist of fine, not too hard grained sand or gravel.
