These are wonderful characterful fish, but they do grow big, about a foot!
Hope you have a suitable sized tank for these guys and they do best in groups of at least 6+ as well.
As for feeding these fish, according to SF in the link above -
"Appears to be chiefly
carnivorous they will also eat
vegetative matter if available, often including soft-leaved
aquatic plants. The natural diet comprises aquatic molluscs, insects, worms, and other invertebrates.
In captivity it’s a largely unfussy feeders but must be offered a varied diet comprising quality dried products, live or frozen
bloodworm,
Tubifex,
Artemia, etc., plus fresh fruit and vegetables such as cucumber, melon, blanched spinach, or courgette.
Home-made foods using a mixture of natural ingredients and bound with gelatin are also highly recommended.
Chopped earthworm can also provide a useful source of protein but should be used sparingly, and while it will also prey on
aquatic snails it should never be considered the answer to an infestation since it is not an
obligate molluscivore.
Once settled into an
aquarium it’s a bold feeder and will often rise into midwater at meal times. "
