Common Fish Diseases

Ich (White Spot) - Ichthyophthirius (freshwater)

Looks like salt sprinkled on the fish’s body and fins. Usually accompanied by twitching, flashing, and other signs of stress and irritation. Several parasites are grouped under this name, but the symptoms are almost identical. Ich is among the most common infections of fish, and is entirely treatable with diligence and attention to water quality.

Suggested Treatment Period:

MetroPlex™ Blend: 14-21 days

Special Considerations

It is very important with this parasite to continue dosing for the full treatment period. A break in the medication allows the parasite to multiply and reinfect the fish.

Popeye

Bacterial infection

Eyes protrude or appear to be "popping out" of the head. Popeye is caused by a buildup of fluid behind the eye and is often seen in conjunction with Dropsy.

Suggested Treatment Period:

KanaPlex™ Blend: 1 week 

Hemorrhagic Septicemia

Aeromonas hydrophilia.

Reddish streaks in the fins near the body or under scales. Common in goldfish. Associated with overcrowding and stress, particularly in goldfish and koi. It can also be caused by a virus.

Suggested Treatment Period:

KanaPlex™ Blend: 1 week or SulfaPlex™ Blend: 3 weeks

Special Considerations

This infection is strongly linked to crowding and poor water conditions. Make sure your fish have clean water and plenty of space. 

Dropsy

Symptom of internal damage

Fish appears bloated, scales stick out in a pinecone-like manner. Dropsy is a result of damage to the liver, causing fluid to build up in the fish. It often starts as bloat and progresses to Dropsy over time.

Suggested Treatment Period:

KanaPlex™ Blend: 1 week

Special Considerations

Dropsy is a sign of severe internal damage, not a symptom of a specific disease. It is treatable with KanaPlex if caught early, but sometimes the damage is too severe to respond to medications. The best defense is to catch internal infections early, before they progress to this stage. 

Mouth Rot

Columnaris

Damaged fins, ulcers and yellowish patches on gills, tissue on head and mouth eaten away. This infection appears gruesome, but is entirely treatable. It is common to see fungus-like tufts around the face and mouth in addition to deterioration of tissue. It is essential to catch this disease early to prevent long-term damage.

Suggested Treatment Period:

KanaPlex™ Blend: 1 week

Special Considerations

Columnaris is very contagious. If possible, remove the infected fish to treat separately in a hospital tank. 

Hole in the Head

Spironucleus

Symptoms include a loss of color, erosion or lesions on the face, head, and body, and stringy white feces. This condition is often caused by an internal parasite, but factors like poor diet, poor water quality, and lack of trace elements will all contribute to this issue.

Suggested Treatment Period:

MetroPlex™ Blend: 2 weeks

Special Considerations

In freshwater this condition is called Hole in the Head. Research your fish’s preferred diet and water chemistry to ensure they are being properly duplicated in the aquarium. Consider using a nutrient soak for the food to provide essential vitamins and nutrients to the fish.
