I'm new to this forum so hello everyone! So, I have a very silly Goldfish! I've had my two cutie Goldfish for 6 weeks now and have noticed that one of them keeps eating bubbles on and off throughout the day, then she eventually starts floating to the top of the tank. Once I notice her buoyancy issue I feed her a cut up pea, she's goes to the loo, then she's back to normal. Do any of you know how I can encourage her to stop eating those bubbles please! I should point out the other Goldfish isn't effected at all, other than this they're very healthy, their ammonia and nitrite is 0 and their PH is between 7 and 8. I use sinking pellets which I've tried soaking to help them pass food in case that's the problem, but really I think i just have a dopey fishy who thinks bubbles are food. This is worth a mention too, my partner noticed she seemed more interested in the bubbles when her tank light came on this morning. Your help would be really appreciated!
