Goldfish (the real kind, not the crackers), sometimes get air stuck in their bladders and need to eat frozen peas to feel better. Interesting isn’t it? Who knew!
To feed them frozen peas, be sure you take off the outer skin of the pea first, and feed the inner part of the pea to the fish. Goldfish like them too, well, at least it seems like they do.
I’ve had to feed peas a lot recently, as one of our fish seems extra prone to getting air stuck. I’m just glad that the peas seem to help.
