Catfish Breeding Tunnels

As the name suggests! We use these handmade ceramic breeding tubes and tunnels to breed catfish. The male, raunchy little bastard, will trap the girl inside and force his way on her. As barbaric as the male seems though, he is actually pretty good paternally and will fan the eggs until they hatch and leave the cave. Unless he gets jack of it and kicks the eggs out prematurely. But hey, some progeny are just 'bad eggs' i guess.
