Answer
Hi Pippa,

Your goldfish may be constipated.
Yes, they do get that.
Just like humans who don't eat their veggies.
To much fat in their food will make digestion slower.
Give them some lettuce leaves for nibbling once in a while. Just place it in the water. Make sure that the leaves are removed after four to five hours.
Green peas are also good for them.

Good luck!
