Hello,
Lately on my tamasopoensis, I have noticed black spots on and around his mouth and underbelly, going back to the tail fin. I have done some research on "black spot disease" on the internet, as I have not encountered this one before, and the info I was able to find seems inconclusive and sketchy at best. Some people say it is from too much spirulina in the diet. I feed a varied diet to my fish, including NLS pellets (staple), hikari cichlid gold, southern delight vegetable grow, and freeze-dried krill. The only fish with these black spots is the tamasopoensis. He does not seem affected by it in any way- he is the boss of the tank and is his usual active self. I dosed the tank with pimafix for a week to see if it would get rid of it, as pimafix is mild anyway. no dice.

To further confuse me- there are not many pictures of tamasopoensis on the internet, as it is a quite rare species in the hobby. Of the pictures they have on google, the best close-up I found also has the same black spots! I have uploaded the picture below. I tried to get a picture of my fish, but it is hard to get one showing the spots. they look 100% exactly like the ones on the fish pictured.tama1.jpg
So, any ideas? Is this probably just an odd coloration on this species, which has not been well documented? or perhaps a disease, fungus of some sort?
 
Parasite infections have been assoc with black spots or blotches on the mouth and nearby areas. Heard of the spirulina as well. But if it's acting normal and eating well then just a plain old black spot.
 
Black spots on fish has absolutely nothing to do with spirulina, that is simply an old wives tale.

While I am not sure about the normal coloration of that species, this past comment of mine explains what black spot disease is, where it comes from, etc.

Thank you RD, that is a much better explanation than I was able to find online. So The bird is missing from the equation here, but I do have snails in the tank. Should I be removing them? If it safe to put the snails in another tank, or do the snails themselves carry the parasite? I have four or five snails in the tank, I'd hate to have to euthanize them but will if they are spreading the parasite.
 
Snails act as a host for the parasite, so yes, I would remove them from the tank. If you place them into another tank with fish, the cycle will begin again. Unless black spots are normal for this species, which I doubt, but maybe check with others before doing anything drastic.
 
If I were to remove the snails, do you know if the parasite can travel back from the fish to another snail? Basically, If I removed my snails, then put in 4 different snails from a different system, would the new snails contract and carry the parasite? I like having snails in the tank, but will forego them if they are going to keep the cycle going
 
Yeah, I state exactly that in the first paragraph of the link I posted. Snails act as a host for this parasite.
 
Alright, the snails are gettin' the freezer. Poor little guys.
Thanks for your help RD. Would rather have some frozen snails than more parasites in my tank.
