So my male betta has recently begun building bubble nests. I just bought him almost a week ago. I was happy to see this because I was under the impression that this is a good sign, in terms of his health and well-being (that it means they're "happy"). But I'm somewhat aware that this also has to do with mating? With my previous fish who did this, I took it as a sign that he was feeling ok and was content... Am I right at all in this?
If anyone has more detailed information on bubble nests I would love to hear it!
