yes.. you can get as elaborate as you want.. spent $30 or $300. just up to the keeper if they want to do things on the cheap that work or invest in a superior system. if you are serious about bettas, it's easy to set up a really nice central system like many shops here in the states have... but if it's just a passing fancy or if you are poor like me, you can do lots of things without breaking the bank..
i did keep some in bowls and it hard work,you do have to keep on top of the water.mine did live like that for a long time.if you go to your lfs some will sell them in bowls and other in tanks.
I know a lot of shops that have gone away from the mass tank, one sump system for the reason i've already stated. I know a guy who had a £20,000 sump system installed in his marine shop........it failed killing 1000's of pounds worth of fish and nearly cost him his business

Most lfs around my way refuse to sell bowls or tiny tanks, and refuse to sell tanks and fish to the buyer at the same time.
