Hi, I'm Bente and I'm new to this forum.
I have a female American flagfish who 3 days ago had a white spot on her eyelid (I hadn't noticed it then, I just saw a pic I had taken and now see it) and yesterday I noticed it as being very large (looks larger than any ich I've seen) and is covering 1/3 of the eye. she is a small fish, though, only 3/4 inch. I had treated for ich about a week ago after aquiring some new platies from a petstore for almost 3 days after seeing the fish flick, but stopped the treatment when my male fancy guppy was showing distress on the aquarium floor as all the fish ate his tail fin. I did a water change and he recovered but never completely so I euthanized him. I assumed he had gill flukes. I've looked for gill flukes at 40X but because I'm inexperienced with taking mucus scrapings I'm not sure if I did a good job at the sampling.
I got some platies a couple of weeks ago and have gotten a new molly from the local saltmarsh (they often have leeches, black or green, and this one had a reddish segmented hooked worm on his tail). Basically I know i have parasites, the question is, is this white spot ich or is there anything else that can be confused with it? From my understanding, ich is old world, but I've caught Sheepshead minnows with white spots on their fins that looked like ich, so I could've gotten it from the marsh presumable as well. I've got a good pic of the spot.
I also had a female Sailfin suddenly get a black splotch on her side that disappeared after 2 days. Now an American flagfish has a new second black splotch on her side and has been there 2 days, she also has a brown spot on her dorsal fin that showed up at the same time.
Any help is appreciated!
