Can We Cover Up The Fish Bowl ?

[a guppy fan]

In any event, do not use a goldfish bowl unless it's for collecting loose change.

... What about fishless aquascapes? not a single animal

I suggest you start a new thread with this question...perhaps put it in the Planted Chit Chat sub-Forum.
It'll get fresh and up to date responses.
(I confess, I nearly choked on my cornflakes reading the title of this thread and was impressed how it was all effectively wrapped up. Opening it up again would not be a good idea ).

Bettas are one of the few fish that can be kept without a filter; but we don't recommend it. All fish do better, will be healthier and live longer in a properly filtered and cycled tank (yes, we're going to have to explain 'cycling' now, I know; 'cycling' is growing a colony of the good bacteria, that akasha mentioned earlier, inside the filter. Those bacteria take care of the fish's waste's for you, so you don't have to be doing water changes every day and, most importantly the fish is protected from a build up of ammonia that can kill it).

We never recommend tanks of less than 5 gallons,

only if planted..
