I have recently lost a few fish for unknown reasons. They had no symptoms, were behaving and eating normally, but just turn up dead.
My dalmation molly has recently started to act sick though, so I know something is wrong with her. We purchased her about a week ago. She is floating near the top and swimming very wobbly when she does go somewhere. She has a few almost unnoticeable rust colored spots on her. The rest of the mollies where we purchased her from did too. None of the spots are spreading, getting larger etc... so I assume it is just a dalmation mollies coloration. She did appear to ram up against a boat ornament that we have in the tank, so I don't know if she was trying to scratch or if she is just a very wobbly swimmer due to her being sick.
I also just noticed that my Guppy
has started to scratch up against the gravel. There are no signs of ich on him or any of the fish. Is this just coincidence or could it be the early warning signs of ich?
Should I go ahead and treat my whole tank for ich and try to nip it in the butt if this may be what it is?
Please help! All of my tank info is listed below.
