[Ebook] 500 freshwater aquarium fish – Catfish – Zamora Woodcat (Auchenipterichthys thoracatus)

There are only two species in the genus Auchenipterichthys, with the Zamora Woodcat being the one seen more frequently in aquaria. It is able to produce a buzzing sound by rotating its pectoral-fin spines in their sockets. The noise is amplified by the swimbladder, which has an elastic spring mechanism that can make it vibrate and emit sounds.

Other common name

• Midnight Catfish

Synonyms

• Auchenipterus thoracatus, Zamora cunchi

Family

• Auchenipteridae

Distribution

• Upper Amazon.

Size

• Up to 5 1/4in (13.5cm).

Behavior

• Nocturnal; not overaggressive, but predatory on small fish.

Diet

• Livefoods preferred, but will accept other diets.

Aquarium

• Numerous shelters are required as daytime hiding places. Water chemistry not critical, but extremes of pH and hardness should be avoided. Temperature range: 70-77T (21-25°C).

Breeding

• Challenging in aquaria. Fertilization is internal and the sperm “plug” can remain potent for several months in, at least, some species of the family. Egg deposition can therefore occur some time after mating.
