All assigned numbers: L399

Location: Brazil: Pará, Rio Xingú (Belo Monte)


For some time, the area around the upper tracts of the Monte Belo region of the Xingu river were fished for L-66. However, more recently, the area has been explored further, and, as a result, a number of new hypancistrus have been coming in, and have henceforth been awarded with L-numbers to match. Granted, these fish are more of a conglomerate of all species found in that particular region, thus, there is some variability within each number. L-399, the first of the two, is a more classically colored hypancistrus, with a light on dark striped pattern and exists in a few like-bodied variants (blame poor classification)—Werner’s photos clearly showcase a number of different fish. It differs from other similar animals by bearing fewer stripes with an undefined pattern. It also has, in some variants, a very distinctly elongated caudal region. The average size of these animals tends to be less than other members of this group--aim for about 4.5", if slightly larger.**

Sexing and Breeding:

An omnivore thats leans towards a meatier diet, so the main diet should consist of meaty foods such as frozen foods (tubifex, mosquito larvae, blood worms, artemia), dry foods (freeze-dried foods, flakes, granules), carnivore sinking pellets, and occasionally some small pieces of shrimp, mussels or fish fillet. Once acclimatized, it will often also accept vegetable matter such as algae/spirulina disks and fresh vegetables (lettuce, zucchini/courgette, eggplant/aubergine, capsicum, carrot, peas, preboiled spinach).
This species usually does not eat algae (it lacks suitable teeth for that task), so it's not a suitable fish to keep your tank free of algae.

Water parameters:
PH 5-7 Temp 26-30cGood water quality is needed, low nitrates and no nitrites. A high oxygen environment with lots of water changes to prevent the build up of any waste,good filtration is also needed. Juvenile 'Belo Monte' may view any plants in the aquarium as food although adults tend to leave them alone

Max Size: 14cms

Additional Comments:

The L399 and L400 could turn out to be the same fish
