A common export from Colombia is the Green Panaque, L191. This is a nice looking species, with a dark, moss-green base-colour covered in irregular black dots and lines. As it grows, the pattern gradually disappears. Adults are more or less uniformly dark green/grey. Keeping L191 is pretty easy and typical for the large Panaque types. When settled they will be active even during the day, and if their basic demands are fulfilled they can even be kept in community set ups. Keep in mind that these are very large growing creatures, and they are also very long lived.

All Panaque species must be provided lots of wood in their environment, as this is needed for their digestive system. They should also be fed a varied menu of vegetables such as potatoes, carrots, cucumbers and such. Additional dry foods like tablets should also be given. If given too much protein rich/fat food their digestive system will suffer. Panaques are large growing fish, so they must be given enough space. A very good filtration system is required to maintain a good water quality and break down the amounts of waste produced by these grazing machines. Regular water changes are of course also essential. They are very peaceful, and will not go after even the smallest fish for food. As they age, males may become more territorial and quarrelsome towards each other. Males develop extreme odontodal growth on their cheeks and pectoral fins. Breeding is very rare in captivity due to the size of the fish, but has occurred. The eggs are placed in a shelter among wood, or in cavities large enough for the adults.
