What are the large amounts of bubbles that have formed in my tank. I can't tell if they are coming from the filter or not. The filter is not helping though. It's just pushing all the bubbles around. Is this a bad sign?
It possibly is. It is hard to tell when the filter just keeps pushing them around. But yes it most likely is coming from the filter. I don't think our betta could make that many bubbles...
my betta made a bubble cluster of approximatelya cirlce of a diameter of 3 inches - just a little smaller than a cd, in like 2 days - and its a lil thick in places too
some fish are bubble nest breeders. the bubble nest is usually at the bottom of the tank though. sometimes i get bubbles at the top. especially with the powerheads. never had problems though. could be the calcium buildup in the water.
