So my Betta, Prince William (see profile pic), hasn't made bubble nests in a while.
We've had him for about 6 weeks. At first he was in a 1 gallon unfiltered tank, but 3 weeks ago we moved him to a 5.5 gallon filtered tank.
The filter's current is a little strong but I've managed to slow it down a bit by putting tall plants under where the water flows. But the current is still strong enough that it keeps popping the few bubbles he gets to make.
He's not lethargic and he eats like normal.
But I read that bubble nests are signs of a happy Betta. I just wanted to make sure that he won't get sad because the filter keeps popping the bubbles that he makes. LOL!
