Name: Hypancistrus Sp 'Rio Curua'

Common Names: yellow zebra

Location: Rio Curua, Para, Brazil


For the last 2 or so odd years, fish imported as L-333, the priciest of the commonly available hypancistrus, began showing up in worldwide markets. In fact, however, it was later discovered that the supposed “new Alenquer†L-333 were in fact from the Rio Curua, a popular residence for several other ornamental loricariids, a number of which are also hypancistrus. The market name of these animals is probably in no small part due to the considerable profits the L-333 namesake reaps, however, in order to be passed off as a different animal, this new fish must have been strikingly similar in appearance, and indeed, it is. The stout, thick body shape of this L number is highly reminiscent of L-333; with it’s large head and body, and the caudal peduncle terminating early in its logintudinal profile. The nuanced differences between the two numbers is limited largely to slight differences in body shape. One of the most prominent features of L-401 is its high, blunt forebody. Whereas L-333 may have a more classically sloping rostrum, L-401 has a more rounded visage with eyes set farther back along its head, not to mention a less posteriorly elongated caudal. Last, while patterning is not often a great way to quantitative L number differences, it should be noted that the vast majority of the patterning in this animal is arranged vertically, relative to the axis of the body, front to back. However, there does seem to be, to no great surprise, a great variety amongst animals imported from this region under the given name, some with lyre like caudals, and more elongated bodies, and more sloped heads. Therefore, it is safe to assume that there are probably multiple species lined up for this number.**

L-401. The bluntly sloping forehead and caudal size are apparent.

Compatibility: L401 are peaceful so can be kept in a community set up with no problems. For spawning purpose as species only tanks is an advantage.

Sexing and Breeding:
Normal hypan set up with slate, Caves and some bogwood. This particular hypan is not aggressive in spawning and usually happens overnight. Spawns are normally between 30 and 50 fry. The fry are very fast growing and will reach almost 2" with in 6 months.

An omnivore that 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:
25-29c PH 5-7
