2 months ago a friend gave me a plant (encharlis or some thing) from her plastic guppy pond.. it had algae and bugs etc... but I just rinsed it in warm water a couple times, hoping that would be enough. The plant has since died along with fish... but I have noticed tiny tiny little bigger than needle point size bugs?

  • Are these parasites?
  • How can I get rid of these?
  • Will they affect fish if I put more plants in later?
  • the first thing i want you to do is google daphnia and cyclops to see if might be any of them.and get a magnifying glass and describe how they look. – trond hansen Mar 11 '18 at 12:56

  • It seems like you should use plastic plants. – blacksmith37 Jul 11 '18 at 16:15

about 99,9% of the tiny lifeforms living in freshwater is totally harmless to fish and most is actually food for your fish.

in your comment you have found them to be cyclops and this is the ideal food for your fish both big and small.

here is a little about the dangerous types even if it unlikely you have any of them in your tank.

most of the external parasites are too small to see with the naked eye so the first sign of innfection is often gray or red skin and increased mucus on the skin.

the other part of external parasites is quite large and easy to see like fish lice and hookworms.

most of the internal parasites is harder to see,different types of worms are the most common in the intestins of fish.

some parsites do atack the gills of the fish,different types of gill flukes they are hard to see without a microscope but one can often see discoloration of the gills in innfected fish.
