Hello everyone,
We have a common comet goldfish that is about 7 inches long (not including the tail) housed in a 20 gallon tank, established for about 2 years. It is filtered by an AquaClear 200, pH is 7.0, 0 ammonia, 0 nitrites, temperature is about 68 degrees. I feed the fish once or twice a day with goldfish pellets by NutraFin, with frequent days of fasting (about 3 days a week). I change about 25-30% of the water about once a week.
The problem is that the goldfish is extremely fat...I would even say obese, very obese. It doesn't seem to be in any discomfort, nor does it have trouble swimming, but it is kind of disconcerting to see it so large, like it is going to explode at any given time. The scales are all stretched out. It's been like this for about 4 or 5 months now.
What can the problem be? I would appreciate any suggestions and steps to correcting this problem. Thanks!
