A previously highly sought after fish which, with recent importation prohibitions on Brazilian loricariidae, has been seeing wider distribution as of late. It is very similar to L-270 and debiliterra, however, it tends to grow somewhat bulkier than the either species. When young, it has an enormous eye radius which makes it easily separable from similar animals. As it grows larger, it still maintains a rather large eye size compared to l-270, and has very posteriorly placed eyes, which distinguish it from debiliterra. It also bears thicker vermiculations on its flanks.**

Fairly peaceful but when cramped for space and without enough hiding places, hostilities can break out, resulting in - sometimes severe - injuries. Despite that, the Hypancistrus furunculus is best kept in a small group, as it will show more natural behaviour and is more comfortable in when accompanied by a number of others of its own kind.
Sexing and Breeding:
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 accepts 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.
Temp 25-29c PH 5.5-7.5
This small Loricarid prefers a dimly lit tank with a good number of hiding places, either created with plants, drift wood, rocks or artificial (pleco spawning) caves. To keep more than one specimen in the same tank, or together with other bottom dwelling fish, you need at least a 40x16" (100x40cm.) tank: this fish can be quite territorial, and when suitable hiding places are lacking, it can be aggressive towards other bottom dwellers. When kept as only catfish in an aquarium, a tank size of 32x14" (80x35cm.) is sufficient, but it is recommended to keep this species in a group in a species tank.
The Hypancistrus furunculus does best in warm, soft, slightly acidic to neutral water (pH 6.0-7,0), oxygen-rich water and a lot of currents. A powerful filter system is recommended, as this fish produces a lot of waste.
Hypancistrus youngsters may require a more vegetable based diet according to Back to Nature Lnumbers book.
