On one of my algae eaters there has been black spot appearing on it. In the past three days the number of spots has been getting larger. The water parameters is good. Does anyone know what this could be?

Thanks, Jim
 
Are the spots on your pl*co small, or are they slightly large. What kind of pl*co's is it? Some naturally have black spots depending on what kind it is. If it is not a pl*co with natural spots then you very well may have black spot disease. You should use Maracide by Mardel, it is used for most external parasites. Hope that this helps, good luck.
 
Agree, parasitic....

Get to the store quick...this will spread.

IIRC, Maracide or Parasite Guard works pretty well.
 
It is on an albino chineese algae eater. None of the other fish have the spots yet. I am at work now. All I have at home is melafix. Will this work or should I pick up one of the ones you listed.

Thanks, Jim
 
Chinese algae eaters have black spots running along their lateral line. As far as an albino, I'm not sure if it would be present. Try to find some pictures of an albino and see if they have this. If not, just keep monitoring it and see if it gets worse. Melafix does not treat this condition. Just go to your lfs and look for medications that treat external parasites.

Once again good luck
 
I have another albino chineese algae eater in another tank and it doesn't have the spots. The spots started appearing a week ago. It is still eating algaes discs i give it. I will do a large water change tonight. When it stops eating, i will treat it than because i picked up the medicine last night.

Thanks, Jim
 
I decided to treat the disease with salt. I started the treatment 3 days ago and now he is recovering. I started the treatment because he started to get really red in the gill area so I came to the conclusion that it was a gill parasite.

Thank for the help, Jim
