What Is Ich?

Ich, or white spot disease, is a parasitic infection that affects fish. The parasite attaches itself to the fish’s skin and fins, causing lesions that can quickly lead to death if left untreated. Ich is one of the most common diseases in aquariums and can result from various factors, including poor water quality, stress, and overcrowding.

How To Identify Ich In Cardinal Tetra?

The most apparent sign of Ich is the presence of white spots on the fish’s body. These spots can be small or large and may spread quickly if left untreated. Other symptoms of Ich include:

  • Small white spots on the fish’s body
  • Spots that spread quickly if not treated properly
  • Fish will become sluggish and may rub up against objects to scratch themselves (this is “flashing”)
  • Gasping at the surface of the water due to a lack of oxygen
  • Red patches on the skin due to inflammation
  • Loss of appetite and weight loss
  • eventual death.

If you notice any of these symptoms in your cardinal tetra, it is vital to take action right away.

Why Are Cardinal Tetra Dying Of Ich?

Ich has a life cycle of about 48-72 hours. It is a white spot disease and transfers from one fish through live food. Along with this, other aquarium inhabitants such as snails or plants exposed to it might also assist in the contraction of Ich. But the most common reason why Cardinal tetra is dying of Ich are:

Stress

Cardinal tetra is very sensitive to changes in their environment and can succumb to Ich quickly if they become stressed. Usually, it can occur for various reasons, such as overcrowding, bullying by other fish, or new aquarium inhabitants.

Lack Of Oxygen

Cardinal tetra cannot extract enough oxygen from the water if there is a lack of dissolved oxygen in their tank. Hence, if your aquarium lacks aeration or filtration, you will need to add an air stone and filter to keep the levels up.

Improper Water Parameters

Water parameters such as pH level, temperature, and water hardness can all affect the health of your fish. Therefore, it is essential to monitor these levels regularly to act fast if they begin to show signs of stress, making it more difficult for them to fight Ich effectively.

Parasites

Ich is a parasite that can affect both fish and plants. Therefore, if you have an infestation of Ich in your tank, it is crucial to treat all of your aquarium inhabitants with a medication approved for use against Ich.

Poor Nutrition

A poor diet can also lead to a weakened immune system and make your fish more susceptible to Ich. So, make sure you feed them a quality diet consisting of meaty and vegetative foods.

Poor Water Quality

Ich thrives in poor water quality conditions. So, if you’re not keeping up with your tank maintenance, you provide an ideal environment for Ich to thrive and spread.

Low pH

Cardinal tetra does best in a pH of around neutral (pH of about seven). If your tank’s pH is below this level, it can cause stress and even death to your fish.

Overcrowding

Cardinal tetra is a schooling species. So, it would be best if you kept them in groups of at least six or more. If you overcrowd the tank with too few cardinal tetras, they will not have enough space for themselves. As a result, they feel stressed out, making them more prone to diseases.

Lack Of Tank Mates

Cardinal tetra prefers the company of other fish species like danios, harlequin rasbora (Trigonostigma heteromorpha), or any small catfish that keeps it safe from larger predatory fish. If you keep them with non-schooling fish, it will make them feel less secure and more stressed.

How To Save Dying Cardinal Tetra?

The cardinal tetra is a beautiful fish popular in the aquarium hobby. Unfortunately, this species is dying from ichthyophthirius multifiliis, more commonly known as Ich. Although you can cure Ich in cardinal tetra, it can be complex.
