The white spots may reach more than 1 mm in diameter and are easily recognized on skin and fins whereas trophonts attached to the gills are hard to see due to the gill cover . Skin: Ich infections are usually visible as one or several characteristic white spots on the body or fins of the fish.
The symptoms and life-cycle are generally similar to those of Ichthyophthirius in freshwater fish, including white spots, on account of which Cryptocaryon is usually called marine ich. However, Cryptocaryon can spend a much longer time encysted. Fish that are infected with Cryptocaryon may have small white spots, nodules, or patches on their ...
Fin rot is most often observed in aquaria and aquaculture, but can also occur in natural populations. [1] Fin rot can be the result of a bacterial infection (Pseudomonas fluorescens, which causes a ragged rotting of the fin), or as a fungal infection (which rots the fin more evenly and is more likely to produce a white "edge"). Sometimes, both ...
Ichthyophthirius multifiliis, commonly known as ich, is a protozoan parasite that infects guppies and other freshwater fish. The infection is characterized by white cysts appearing on the skin, gills, and fins of the affected fish, giving a distinct white spot appearance which is often referred to as "white spot disease".

Ich, also known as "White Spot Disease," is caused by the parasitic protozoan Ichthyophthirius multifiliis. Fish infected with Ich exhibit small, white, grain-like spots on their body, fins, and gills. [5] These spots are cysts where the parasites reside.

The spots located on the rear of A. meleagris are more minuscule compared to the spots on its sides, a characteristic that is especially prevalent on those that are located in the Indian Ocean. [2] A majority of the specimens of A. meleagris have pale fins that are dark brown in color with white spots not unlike to the ones found on its body. [2]
This causes the epidermal cells to proliferate and form pinhead-sized white spots that appear on the fins and body. It is usually introduced into the pond or aquarium on infected fish or contaminated equipment. Once considered a tropical fish disease, it is now a common goldfish illness. Fish may not always display the characteristic white spots.
The adult fish has a dark greenish-brown body with an elongated white spot on each scale. Its head is gray-blue with brown lines radiated from the eyes. Two black spots occur in front of the dorsal fin and a wide vertical white bar is found on the base of the caudal fin. The posterior part of the caudal fin and the pelvic fins are black.
