I woke up this morning and found my royal gramma dead and he was acting fine and eating normally yesterday. Of course I tested everything right away this morning and I had no changes in my water parameters. However later this afternoon I noticed I had rust spots (real rust, not an algae) on my glass. I had one of those magnetic glass cleaners that I just put back in the tank the other day and I had it hanging in this spot. I never would have thought it would have rusted on my glass but apparently it did and I'm thinking that is what killed the fish? I have 3 chromis in the tank that I pulled from it as soon as I found the rust and I'm having a heck of a time scraping it off. Razor blade finally got most of it off but there is still some on there I just can't get off the glass. Any advice and how bad is my tank now? The rust spots were about 1 -2 inches wide and 3 inches high. Exactly the outline of the darn glass cleaner. It is a FOWLR, about 5 months old. I've been trying to find some other posts on rust and haven't seen any yet.
Thanks all for any advice you can give me. Oh, I also noticed tonight that I now have some white thread like algae starting on the glass that was not there about 3 hours ago. Would that come from this as well?
