Black spot disease

  • We are currently upgrading MFK. thanks! -neo
You could also treat using salt baths or dips. I treated parasites on my ranchus with short salt dips. Remember, a salt bath is different from a salt dip. I prefer salt dips, because they are quicker and stronger, but they can stress out your fish, so i only use salt dips for hardy fish, like goldfish.

Thanks for that tip, I really appreciate it. I'll be adding aquarium salt from tomorrow onward. I have a couple of final questions left though. After 30 days has passed, if my angelfish shows no sign of having deteriorated (as of now, apart from the little black pimple, she seems perfectly fine), would it be safe for me to assume that she has recovered? On an unrelated note, she is clearly uncomfortable about being in a bare tank. Would it be alright if I were to add some live plants? Or would plastic ones be a better choice? Again ,thanks so much.

The black spots should go away after 30 days. At least keep the tank bare bottom. You can add some fake plants if you want.
 
With true black spot disease, the parasites remain encysted and never go away; the life cycle is completed when the fish is consumed by another predator

Will her health continue to be in danger though? And will the parasite continue to remain contagious to other fish? Again, thanks.
 
Here's a little background from the DNR:
These parasitic flatworms appear as tiny black spots on the skin, fins and flesh of fish. No method of control is available for the elimination of this problem. This organism does little harm to the fish. The main problem associated with black-spot is the unsightly appearance it may cause. Skinning infected fish will remove most black spots.

The life cycle of the parasite is quite complex. A fish-eating bird (typically a great blue heron or kingfisher) eats an infected fish. The black spot or worms are released and grow to sexual maturity in the bird's intestine. The adult worms pass eggs with the bird's droppings. When the eggs reach water, they hatch into free-swimming organisms which then penetrate snails for further development. Finally, after leaving the snails they burrow into the skin of fish and form a cyst. The fish surrounds the cyst with black pigment that gives the disease its name. If an infected fish is consumed by a bird, the cycle repeats itself.

I would dose with PraziPro if this fish hasn't been treated before to eliminate others species of trematode/nematodes, just as a precaution.

Additionally, do trematodes infest the inside of the fish as well? Again, thanks for being so helpful.

They are typically found externally but some species are internal....
