Hey ,
no need to be harsh. SOme people have differents things to to on x-mas time as looking into online boards.
IMHO keeping channa in bare everything tanks is a cfruelty to the fish and just a sign of stupidness of the keeper that does not want the fish behave like natural and just sees the fish as a decoration to his home , and not as an living animal with special needs.
From keeping and breeding channa over some years I learned:
The more hiding places the better
The more hiding places the more active is the fish
the more hiding places the less these are used by the fish caus it feels secure, when it can hide everytime it wants to. So there is no need for the fish to stay close to one hiding place.
The other thing is fish in bare tanks look loke fish ini aquaria of shops selling fish for food purposes. I think this looks ugly, and I dont wanna have such things in my home.
