Too Many Bubbles?
I have a question. I have a 30 gallon tank, with three goldfish. In the evening, after I feed them, when I look over at them they tend to be on the top, either just floating there, or swimming around like they need air. They aren't swimming around down in the tank much. I have a bubble wand that goes around three sides of the tank, making lots of bubbles. Last night we were without power for about three hours, so no bubbles. I positioned one of the flashlights into the tank, and as I watched them they swam around down in the tank like they're suppose to do, not really going up to the top near as much. So, my question is, can one have too many bubbles?
Thanks a bunch, Lauri
