Diseased Fish (Pictures)  

post #1 of 15
Thread Starter 

A picture is worth 1000 words so here we have a collection of pictures of fish with diseases.

By posting a picture here, I am asking fellow hobbyists to contribute to the Diseased Fish Thread which will go towards helping other aquarists who can not post pictures.

If anyone prefers not to have their fish's picture posted here, please just let me know.

Thank you for your contribution to this hobby!

Brooklynella

Brooklynella is a parasite seen most frequently in clownfish, so its sometimes called "clownfish disease"; however, other fish are certainly susceptible to this parasite. The most effective treatment is formalin bathes.

The first 2 pictures are courtesy of Steven Pro.

Hyper-Melaninization

Clownfish with dark pigmentation resulting from a reaction to stings from a coral or anemone. This usually poses no notable problem to the clownfish. The melanin [pigment] darkens as it reacts to nematocysts (sting cells).

Cryptocaryon irritans [a.k.a. Ich or Ich]

Ich is commonly treated using hybosalinity or copper. Cupramine is the most stable copper product. It requires a compatible copper test kit.  Hyposalinity is equally as effective and does not expose fish to toxic parasitic medications.

Cryptocaryon irritans

This hippo tang is seriously compromised by the ich parasite with degraded flesh and fins ( head ad lateral line erosion -HLLE),  and a secondary eye infection causing pop-eye.

Head and Lateral Line Erosion [HLLE]

Treatment

 

This poor yellow tank is suffering from:
-HLLE [the eroded flesh]
-A bacterial infection [the red and bloody blood vessels]
-Malnutrition/emaciation [the sunken abdomen and rips]

Classic HLLE, with erosion along the lateral line of the fish, and circling the eye

Hippo tang with HLLE along the lateral line; also erosion circling the eye and below the eye. Spots of erosion pocking the body

Not too often pictured, a lionfish with HLLE.  Harder to detect because of the fish's natural markings

Black Ich

Black ich  is not exclusive to yellow tangs. This fish species' solid light color makes the parasite more visible.

Lawnmower Blenny suffering Malnutrition

The lawnmower blenny has a specialized algae diet. Hobbyists frequently get lawnmowers to address Filamentous Algae [nuisance problem] in their aquaria. After a few weeks when the lawnmower blenny has eaten all of the problem algae, there will be no more food and he will slowly starve, as in this specimen.

Bacterial Infection

Yellow tangs with obvious bacterial infections. Note, red, and inflamed areas beginning along the body above the anal fin, encompassing the rear end of the body and spreading to the dorsal area. Typical vulnerable spots along the lateral line in tangs.  Even the area above the eye and around the gills are showing symptoms. Sometimes this type of infection will appear as red streaks or splotches that look like hemorrhage beneath the skin of the fish.

Pop-Eye

Bulged eye can be caused by several stresses: injury to the eye and bacterial infections are the primary culprits. Oftentimes, netting a fish can cause popeye from direct injury with the net, or because of bacteria on the net itself. When at all possible, avoid using nets, and always keep fish in water. If you are going to use a net, however, sterilize it before use and place some slime coat on it just before you capture the fish.

Stressed Fish

Stress can result from disease, acclimation, aggression from other tankmates, poor environment, poor nutrition, etc.

 And finally, back to normal!  Well, almost....still a faint shadow of previous scaring.
