I'm getting kind of worried about Aquarius, I have had him almost two weeks now and still no bubble nests. At first I thought it was the filter so I shut the filter off for a good three hours every day to give him a chance but he never builds one. Then I started thinking maybe he is too young and just not old enough to think about breeding thus has no reason to make one, but now I wonder if he's just in a small tank and unhappy with it. It's a five gallon tank with a heater set to 78 and a low powered filter that hardly rippled the surface. Why isn't he building any nests? Is it because I have to do two water changes a week because the tank is being cycled and he's stressed out?I have never had a betta who didn't start building bubble nests a week after I got him.
