Signs Of Infection

Similar to False Neon Disease. Pale white patches appear under the skin beneath the dorsal fin. The fish also becomes emaciated and may swim erratically.

When symptoms show suspect False Neon Disease as an alternative.

Fish Affected

Primarily Characins. Originally found in Neon Tetras hence the name but also prolific with Cyprinids such as the Danios.

Details Of Infection

Unlike False Neon Disease, Neon Disease is caused by a parasitic single called organism called Pleistophora hyphessobryconis. The cell, releases millions of spores in to the water during reproduction. The spores are consumed with food by the fish where they then entre the intestine. The spores grow and replace the muscle fibres weakening the fish. If an infected fish becomes wounded or dies, the spores can escape and infect a new host.

Treatment

Commercial remedies are usually ineffective as by the time diagnosis is confirmed the fish is too weak to be saved. Infected fish should therefore be removed immediately to prevent further infestation. The problem occurs when attempting to rid the tank of free swimming spores. Often the only solution is to strip down and disinfect the aquarium however, some aquarists suggest that using a diatom filter can trap the cells and clear the tank.
