Size 110mm or 4.3" SL. Find near, nearer or same sized spp.
Identification L397 is noted for its bold orange and black bands on the body and fins. On the body and fins of juveniles, and on the fins of adults, the orange and black bands are separated by transparent or white bands. In adults, the orange bands on the body may remain orange-red, or mellow to a shade of brown, but the fins retain an orange-red hue. Another character of L397 is the facial markings: Early in life, the face develops densely packed thin orange and black longitudinal lines, which twist to give the face a slightly scrolled pattern. The abdomen can be white or patterned.
Sexing Mature males can be easily identified by the presence of odontodes covering the caudal peduncle. Most similar-sized females will entirely lack these odontodes and will be wide-bodied when full of eggs.

Jump to next section Husbandry Information
Feeding As with other Panaqolus, vegetables (e.g., yams, courgette, Brussels sprouts) and wood should form the core diet for L397. Also, these fish will eagerly eat meaty foods such as shrimp, clams, and live black worms; a meat meal about 1-3 days per week can help condition the fish for spawning.
Furniture Cobblestones and wood pieces. Plants may be damaged so are not necessary.
Suggested Tankmates Other Loricariids, corys, tetras, and community-compatible cichlids.
Breeding Females lay between 25 and 40 eggs, around 6mm in diameter. Males care for the eggs and fry. After approximately 7 days the egg-sack is consumed. The fry aren't particularly sensitive, but should have access to soft wood to chew on; this combined with algae tablets and a little bit of high protein food will have them grow quickly and are sexually mature after around a year. They will spawn in ceramic caves, but seem to prefer caves made from bamboo, but they will chew this type of cave to bits. Spawning takes place at a temperature between 26 and 30C and a conductivity between 200 and 700 uS/cm (around 125-450ppm TDS). Circulation needs to be good but not strong.
