I saw local pet store sells security house to put in bigger tank to house betta. I have 10g and 2g tank. I am considering female betta. Do you think betta will be happier in the security house inside 10g tank or in 2g tank by itself. 10g tank already has some fish in it. Putting betta means I cannot get anymore fish for 10g tank as I seen betta can easily grow to 3 inches.
thanks
