One could raise a chlid in a closet,or an Eagle in a bird cage. I wonder would they be happy??
Betta's in my view, are the most abused fish in the hobby.I would alway's promote larger quarter's over what is smallest suitable container.
I expect it could be done,but is not much of a step above the tiny cup's they arrive at stores in.
You've read my my thoughts ,somewhat ,it's why I asked.....I am sure that the fish would live ,but are they really happy?
The positive would be to pick a really unhappy one from a tiny tiny cup ,and give it a (somewhat)better life.
The only place I could put another tank is on a massive pinewood night table from Ikea.And I don't dare to go more than 4 gallons ,notice the word "Ikea".
I tightened the screws very well ,and placed it with one side against a wall ,and one of the opposite legs against a fake brick fireplace.It is stable enough ,I even sat myself on it and didn't made any noise ,but I really don't dare go bigger.
I always wanted a Betta ,but that really is the largest I can go with the tank.
