Your goldfish keeps floating to the top on its side what is wrong?

Answer 1

It probably has swim bladder disease. Swim bladder disease is when your goldfish is constipated, and the food is just building up in its stomach. This also happens when you do not soak their food and there is still air in the food and its puts air in the goldfishes stomach and therefore makes it float. Allow me to warn you this disease could be fatal for your goldfish if not treated. My goldfish had swim bladder disease, and this is what I did to help-

1: I made to sure there was little to no ammonia in the tank

2: I withheld food for 2-3 days. The last thing you want to do is add more air in there and possibly some of the food will digest and your goldfish will be relieved and you may have to do anything else. (Although I wouldn't count on it, this helped my goldfish but didn't stop the SBD. (Swim bladder disease)

3: This could also be caused because of lack of greens, vegi's, and fruit. Your goldfish can't live on a diet of pellets forever. Offer it greens at least 2 a week, or you can get a little clippy thing and you can put some lettuce in there. (My four goldfish chomp down a big piece of lettuce fast, they really love it. But I wouldn't recommend leaving it in there for more than 2 weeks) Also, give them a small slice of an orange. My goldfish love Oranges, and I think that the orange really helped my goldfish. Don't leave the orange in for more than four hours because the citrus can bring up the ammonia.

4: Remember: Ryukin's and Pearlscales are prone to this disease because of their round shapes. (They are also prone to dropsy) Almost anyone that works with goldfish will have to work with this disease at least once- so that's ok! Good luck to you and your goldfish!!
