Jump to next section Species Information
Size 100mm (3.9") SL. Find near, nearer or same sized spp.
Identification A detailed account can be found in the Catfish of the Month article (link below).
The species is sometimes confused with LDA068, which is very similar, but grows larger. The main key for distinguishing them is that juvenile LDA068 have stripes/squiggles/scribes on the head, which only appear in mature Panaque maccus. The mature size of LDA068 can be over 100mm, something not seen in P. maccus.
Sexing Like all members of the genus, males grow elongated interopercular odontodes during the breeding season. Males develop noticeable odontodes along the dorsum as well.
Jump to next section Habitat Information
Distribution P. maccus is found in Andean whitewater rivers flowing through the Llanos into Rio Orinoco. Rio Apure drainages and reported from Rio Caroni.

pH 6.8 - 7.6
Temperature 23.0-28.0°C or 73.4-82.4°F (Show others within this range)
Other Parameters The aquarium water should be clear in colour with neutral values. Measurements taken at the Rio Tinaco in the dry season were temperature 80°F, pH 7.5, and fairly hard at 3,000 mu. In the wet season the water is cooler, softer and has a neutral pH due to the heavy rains.
Jump to next section Husbandry Information
Feeding A wood-eating fish, the tank should be decorated with several different types of driftwood. These fish really like to have something to chew on and squash, cucumber, and other vegetables should be readily available to them (yams are a favourite). Supplement two to three times weekly with frozen foods.
Furniture The Biotope: P. maccus are only found amongst driftwood tangles close to the banks in the main river channels. Their striped brown and cream coloured body provides excellent camouflage in this environment. Place various types and lengths of driftwood at slanting angles from the back of the tank to the front. The back and sides of the tank should be covered with a dark background. Use sand or fine gravel that is a red-brown in colour for the substrate. Hide the spawning caves along the back of the tank behind the driftwood.
Compatibility A peaceful fish well suited to the community tank provided it has driftwood. The tank must have good mechanical filtration as these fish produce lots of waste from their steady diet of wood.
Suggested Tankmates Other loricariids, small cichlids and tetras. In a small tank (15-20 gallons) add a school of small tetras. Silver hatchet tetras were common in the Rio Tinaco. A larger tank can house a community of wood eating loricariids. Other loricariids caught side by side with P. maccus included: Hypostomus plecostomus, Hypostomus emarginatus (L 153), Hypostomus plecostomoides (L166), L092, Hypoptopoma, Otocinclus, Lamontichthys llanero, and Glyptopterichthys (L154). A tank with this many wood-eating loricariids requires heavy filtration and frequent large water changes.
Breeding The fish should be maintained for two months under dry season conditions (see above) with thrice weekly feedings of frozen foods. In preparation for breeding, add a power head and air stone to the tank, unplug the heater, and begin making 20 percent daily water changes with cool rain or reverse osmosis water. The temperature should be allowed to fall to 70-72F. After four water changes, plug the heater back in and wait for the spawn. If, after one month, the fish have not spawned start the process over again. It may take a few cycles to get the fish spawning. Provide various sized spawning caves made from PVC or slate. The caves should be just large enough to allow the female (which is larger) to squeeze in and five to six inches in length.
