so, i've had my male halfmoon (delta?) betta, little red, for about one month, and i've kept him in a 2.5 gallon tank with plastic plants, a cave, and flat-bottomed marbles. the temperature is a constant 78-80* F throughout the day and 76-78* F at night. i make two water changes each week: one 50% and one 95%.
he's active, he eats, he seems happy, but he doesn't make any bubblenests. i've heard people around here say that they have had males that were ill or stressed, and they still made bubblenests because they said that it's instinct. if it's instinct, why doesn't he make any?
i always thought that males made bubblenests if they were happy, so is he not happy? i just want him to be happy and healthy, and it'd be nice to see him make a bubblenest. (:
