I've have just joined I have a 32l tank with a dozen neon tetras who are lovely active little fish and a 25l tank with my new beautiful beta. He is 6 weeks old and seems very happy. I was wondering when he will start to make bubble nests or is it normal that he hasn't yet. I have had him for 2 weeks now. He has lovely character and greets me when I go to talk to him. I can watch him for hours.
