Koivet.com Resources for Fish and Koi Diseases, Illness Symptoms, Diagnosis, Treatment and Cure

Youtube has provided me with an avenue to reach lots of people with valuable messages about fish health. Saving Koi, goldfish and tank / aquarium fish has been a "thing" for me for decades and I've made a name for myself that way. Which is a double-edged sword. (My Youtube Channel) I like helping people? But not constantly. And folks need to learn on their own, a little, too.  So when people call the office […]

What is the Most Important Fish Water Quality Parameter?

Some would argue that it's Ammonia. The FIRST product of the nitrogen cycle and the primary waste product of fish.  Environmental Threats to Goldfish Health. Youtube Video about Ammonia with Dr Erik Johnson Goldfish health is impacted by far more than just the ‘way’ we care for the fish, or the parasites they may contract. Indeed, their very environment is often the greatest threat to their survival. This is especially true in new, unbalanced systems […]

Fungal Infections In Koi and Pond Fish: White Cottony Growths

Fungal Infections Fungal infections in Goldfish are relatively common, but they always tend to represent the same thing. First, let’s talk about the clinical appearance of a fungal infection. The gross visualization of what appears to be a fungal infection is an unreliable means of diagnosis. Fungal infections usually appear as small to large tufts of white cottony material in the skin and fins of affected fish. The diagnostic challenge is that columnaris bacterial infections […]

Protein in Koi and Pondfish Food

What Protein is and does Protein is what your cells are made of. If it's a cell, it is made of protein. The most numerous cells that are made of, and thus supply the most protein are muscle cells. But one must also remember that red blood cells and infection fighting white cells are also made of protein. People forget that these red and white cells have a finite life span in the blood stream […]

Flukes or Trematodes in Koi and Fish Ponds

Flukes Monogenetic trematodes are a separate class of parasites from ciliated protozoans. The monogenea do not have an intermediate life cycle off the fish. Those trematodes that do are called Digenetic trematodes, and use a bird or a snail as an intermediate host. These are not a considerable pathogen of Goldfish and so we are limiting our discussion to the far more common monogeneans.    The common monogenean trematodes of Goldfish are of the genus […]

Tadpoles and the Pond

Tadpoles Controlling amphibians is not easy – but hatcheries try to control them, especially tadpoles, because the tadpoles take up space and use valuable resources in terms of oxygen, food, while contributing to waste production, for no net financial gain for the farmer.  Control: The growers try their hardest to catch the tadpoles while in the "egg mass" – these appear as gelatinous masses floating in the water with small black spheres in there. They […]

Use of Salt Against Parasites

This may be the most important article / video folks will see this Spring because for a LOT of people with sick fish, SALT at 0.3% may be the fastest and easiest way to limit fish losses AFTER testing the water to make sure it's not as simple as a low pH (ha ha ha) If it's NOT water quality, maybe it is a parasite and MAYBE you can nail it down with Salt.  Here's […]

You Should Know The Cycle

If you are not already familiar with the CYCLE, this is the process by which fish wastes and other debris are broken down by bacteria in an aquatic system. Let’s trace it here. The Cycle is a short series of bacterial reactions that purify water. Ammonia is produced by the fish, from gills (75%) and vent (25%). *Nitrosomonas* bacteria in the gravel break the Ammonia down, *before* it has a chance to accumulate and harm […]
