Parasitic Infection

If your fish’s poop moves around, especially in still water, your fish may have a parasite. We recommend taking it out and putting it in one clear plate or cup to see if it moves. If it is not, your fish situation is not serious.

These parasites might be intestinal worms or intestinal protozoa.  If the cause is internal protozoa, it might be Hexamite or Spironucleus. If the problem is in intestinal worms, it might be roundworms or tapeworms.

If fish suffers from these causes, we recommend separating the fish to avoid infecting others. Afterward, take it to a vet or aquatic doctor to receive appropriate treatment.

Bacterial Infection

It is more common than a parasitic infection. Although white stringy feces is one common sign of that infection, it is not always.

The bacterial infection, such as swim bladder, bloated stomach, rectal infection, and dropsy, lead to white fish poop.

Just keep an eye on fish and cure them if they seem to be struggling with those common infections, and the problem should go away.

Taking your infected fish to a veterinarian is the best way, allowing you to understand which one of those bacterial infections is the cause.

How Do My Fish Poop?

The fish poop’s scientific name is detritus. Like mammals, your fish release poop through their anus at the end of the alimentary canal.

Once this alimentary canal has been full, it will push the waste material out of your fish’s body.

Fish poop comes in many colors. You may see brown, white, green, and pink fish poop. The truth is that your fish poop will depend on what they eat and what the food looks like.
