I need some advice. I have a Betta sorority in a cycled tank and one male Betta in a 21 litre cycled tank on his own. I've come across a gorgeous male Betta I really want but I have no more tanks and no room for one.
I do have a really big glass bowl. It's round. I also have a small spare heater. I'm considering having the bowl on my desk with gravel in the bottom and the heater to keep him at the right temp. But I'm scared because I've never not had a filter. How do people do it? Do you empty it daily? How do you go about cleaning it? Do you take all the water out each day?
Can a Betta live happily in a bowl?
