I have seven Siamese algae eaters, about five are showing small symptoms of something?? They have white (“ashy”) patches that seem to follow a scale pattern. The white patches are not “fuzzy”, and do not follow any of the progressive symptoms that bacteria or fungal infection seem to follow. Does not seem to be highly contagious because some algae eaters are completely fine, they do not look like they have been “sprinkled with salt” (like ick). Additionally, they have been suffering with these patches for quite a while (months), and they seem to not be responding to any medication that I have tried. All of my tank inhabitants are eating and swimming just fine, foraging for food, and chasing each other as normal, no one is hiding off or being bullied. (IM SO CONFUSED!)
Had the siamese algae eaters three months before any symptoms appeared, they have been suffering with whatever this is for over 5 months. Has not affected ALL algae eaters, about 4-5 of the 7. Illness has not spread to betta fish, or a common pleco even though they have been in close proximity, and same environment for months. I tried to use a combination of furan-2 and kanaplex(for five days), I quarantined the entire siamese algae eater population, but that didn’t seem to help, I also used an ick cure from API with no change.
My only possible thought is when I’m not watching maybe they are fighting? Or maybe scratching themselves against something? Although, they have not been exhibiting any scratching behaviors, no rubbing against rocks, or hard scapes, they haven’t really shown any signs of skin Irritation.
