UK catfish judge and frequently featured writer in aquatic magazine circles, Chris Ralph introduces this months featured catfish.

Brochis multiradiatus is one of the largest of the Brochis group of catfish and is very popular amongst a number of catfish enthusiasts myself included. Unfortunately it is not commonly available to the hobbyist. When this truly majestic catfish is available expect to pay £15-£25 for an adult fish. When observing these catfish the aquarist is taken in by the ability of this catfish to almost "wink" at you (Brochis multiradiatus along with its close cousins the "Cory's" can roll its eyes).

As with all the other Brochis that I have had the pleasure to keep over the years, Brochis multiradiatus readily accepts a mixed and varied diet. I personally feed all of my Brochis on sinking catfish pellets, good quality flake foods, granular foods, cultured whiteworm and frozen foods such as bloodworm to name but a few.

The base colour of the body and head varies from a dull brownish/grey to bluish or greenish metallic coloured. The lower half of the ventrolateral body scutes can be light yellow to light pink in colour. A good specimen will have a true emerald green colouration to the flanks and dorsal area, with a pinkish tinge to the ventral region. There can be a presence of colour in the fins of juveniles, but this disappears as the fish matures leaving perfectly clear fins in an adult. The pectoral fin spines are coloured.

I would suggest a minimum size of 30'' x 15'' X 12'' for a shoal of these fascinating catfish. The preferred substrate for keeping these catfish should be good quality aquarium sand such as BD Aquarium Sand, or very smooth rounded gravel in order to prevent their barbels from being damaged. The aquarium should provide some shelter in the form of rocks, bogwood and aquatic plants. As with all other species of fish, water quality and general husbandry is very important, and I would recommend that a minimum of 25% water is changed on a fortnightly basis.
