Distribution and habitat
The crepuscular to nocturnal Red Longfin Ancistrus is a breeding form. Due to mixing with various Antenna Catfishes, it is not possible to determine their origin. Ancistrus wild forms stay mainly in shallow water with stones and dead wood.
Maintenance
The aquarium should have a robust border planting with stones, caves (catfish burrows) and roots, which provide hiding places and at the same time are part of the food. A substrate of sand and round-grained gravel, subdued light (floating plant cover) and a medium current is ideal.
No ammonia, ammonium and nitrite should be detectable, the nitrate value should not exceed 100 mg/l. To ensure the water quality and oxygen content, a filter and heater adapted to the aquarium size is required, as well as lighting for the species-appropriate day-night rhythm of the animals.
Diet
They eat the vegetable cover (growth) of stones, wood, plants, etc. and the microorganisms contained therein. For a balanced diet, feed once a day with a high-quality dry food for loricariid catfish (granules, pellets, chips, tablets), supplemented with algae leaves, soft wood and fresh vegetables, such as zucchini, broccoli, bruised peas or scalded spinach, plus occasional small amounts of zooplankton, cyclops, daphnia, artemia, mosquito larvae, etc. (live or frozen). Feed only as much as will be eaten within a few minutes, excluding plant foods. Regular and varied feeding promotes health and increases resistance.
Behaviour and compatibility
They are calm, peaceful catfish that are somewhat territorial only during spawning season and are very suitable for a community tank with other calm fish. It is recommended to keep them in pairs or in a group of 3-5.
Basically, only compatible fish species with similar demands on water conditions and water temperature should be socialized.
Sex dimorphism
Males have more tentacles on the head and more odontodes on the first pectoral fin ray than females.
Reproduction and breeding
The female spawns in caves or under roots. The clutch is cared for by the male. After about 11 days the fry swim free and must be fed several times a day
Grinded dry food, Artemia, Cyclops and small cut vegetables are suitable as rearing food. In a community tank breeding is hardly possible, because the fry are easy prey.
Important
They have a strong sucking mouth, with spoon-shaped teeth for scraping wood, and intestinal flora that allows the fish to digest the cellulose.
When fishing, use the finest mesh nets possible to prevent the hard rays of the pectoral fins or the skin teeth (odontodes) from getting caught on the bone plates, which can cause painful puncture wounds when touched.
The well-being of the fish should be checked regularly. Temperature should be checked daily, pH, hardness and nitrate levels at least every 14 days. Regular partial water changes are recommended, even when contaminant levels have not yet reached the upper limit. Sudden changes in water quality should be avoided. Newly introduced fish must be accustomed slowly to the water in the aquarium.
