Soooo my mum bought a betta from the pasar malam and it's living in one of those small box containers now. After researching a bit, I realize I need a proper cycled tank but it'll take 4-6 weeks to get there in the meantime, what can I do to make the existing container habitable? Do I just change half the water everyday? Worried that the damage will be done before I can transfer it to a proper tank.
