My goldfish is very constipated fecal matter is about 5 inches long and that is 2-3 times a day the last one was very thick and dark. I actually had to break it off with a spoon for him he was swimming around crazy and very stressed. I gave him a pea, and now waiting to see what happens he keeps swimming to the top gasping for air what else could be the problem?
Hi! What size tank? Tank mates? Exact numbers for ammonia, nitrite, nitrate & ph? Temperature? Is this fish or any other fish new? What do you normal feed him? Gasping at the surface indicates a serious water quality issue such as high ammonia and/or nitrite or a lack of sufficient oxygen. Some more information will help us to figure out what's going on!
