I think fish enjoy a more natural enfironment. just like a person or a dog.
but who knows, we cant talk to fish, i guess we just assume.
butits a space thing
some tanks i have seen are so small, that the fish can only swim one length of its own body accross, cruel really, sad.
but hey, not here to start arguing, its more, i think, aquascapes are great for aros. looks nice.
i particularly do not like bare tanks... unnatural, boring -
