Why Is Goldfish Poop White?

There are a number of different reasons that your goldfish might have white poop. However, no matter what the cause, if your goldfish has white poop the chances are there’s something wrong. Here are the most common causes of white poop.

Poop That Is White, Stringy And Lumpy

If your goldfish’ poop is white stringy and lumpy there are a number of different causes that could be responsible.

  • Poor Diet – The first potential cause is a poor diet. You should be giving your goldfish a mix of live food, meat, tropical flakes, and vegetation. If they’re not getting all of this, then it may turn their feces white.
  • Internal Bacterial Infection – Another common cause of this kind of poop is a bacterial infection. Along with white, stringy, lumpy feces, you may also notice that your goldfish is bloated, lethargic, and has little appetite. Fortunately, if you catch a bacterial infection early enough, it is possible to treat it with the right fish antibiotics.
  • Internal Parasites – Lastly, your goldfish may also be suffering from internal parasites. Tapeworms and roundworms will be the main culprit, however, in extremely rare cases it could also be Hexamita. Fortunately, though, it’s still unlikely that goldfish in tanks will suffer from internal parasites.

White Poop That’s Pale/Transluscent

You may also notice that sometimes a goldfish’ poop is pale or even transluscent in color. When this is the case it means you’re probably underfeeding your goldfish or there’s just not enough nutrients in their diet.

Essentially when poop is pale or translucent it means there’s not enough food in it. At this point, you’re not actually looking at poop but rather the mucus coating that’s inside all goldfish. You should try changing their diet to one with a lot more animal proteins and vegetation in it, as well as high-quality fish flakes. However, if this still doesn’t work then you should speak to a vet.
