So today I went to my local fish store to tell them that one of the glass fish I bought there over a week ago has ich. Now this is a "big box" pet store keep in mind. I led one of the associates to the glass fish tank to show them and the glass fish still in the tank were now covered in spots on there fins. I said your fish obviously have ich! The lady tells me at this point that its not ich at all but its lack of salt. I dont want to take her word for it, but none of my other fish are showing signs at all. She said glass fish and mollys are accually brackish water fish. Im treating for ich now with salt (1 1/2 tsp per gal) and heat (82-84). If its not ich I want to turn down the heat, possibly lower the salt also. The spots are leaving the one glass fish but if it is ich this may be the time to kill it. What the heck should I do folks?
