||Dorsal spines (total):
1 - 1; Dorsal soft rays (total): 4 - 5; Anal spines: 1;Anal soft
rays: 90 – 95. Caudal fin with 17 rays. Occurs mainly
in large lakes and rivers, though occasionally enters brackish
water in the Baltic and Black Seas. Found in deep waters of dams
constructed on the lower reaches of rivers. Known to feed at night
on ducks, voles, crayfish and small fishes. Spawns in the salt
water of the Aral Sea (at Kulandy). Aquarium Care:
You can of course keep small Wels Catfish in an aquarium where
feeding is no problem with dim lighting and a large external filter
and they will eat anything ( just keep an eye on your household
cat), but where would it go after outgrowing your
tank as Public Aquariums have probably their full quota. As they
are very predatory, you should never keep it together with smaller
fish, because especially the small ones can swallow very big things.
You should also get it some kind of shelter like a root or some
kind of tube. Diet: You can actually keep a Wels
in an aquarium as long as it is small enough, but you should NOT
give it normal catfish food which contains a lot of plant-material.
S. glanis is a highly carnivorous predator and will eat
a lot of things. Worms are very good, as well as, dependent on
its size, insect larvae. Crushed snails also work, but if they
get bigger you should mainly feed them with fish. They will even
eat dead fish or chunks of it, and I have often read that they
even eat normal meat and squid in aquariums, but over a longer
time this is possibly not that good.
