I do 40% water changes every week, and I clean the gravel also. I do the filter about every month cause its pretty clean most of the time.
I now am veryy worried, one of my neons is starting to go to the top of the tank and flip over, and my gouramis are both sitting at the surface gulping air and won't eat. I did a water change as soon as possible, and they still aren't doing anything
the platy still has red gills and her fins are down, which I heard is a sign of stress. the rest of my neons are totally fine and are colorful and happy.
I really love these little fish and I don't wanna lose them cause of this
Should I do anything else besides the weekly water changes, etc? EDIT: my gouramis seem super weak. the filter is not strong, and yet they keep being pulled onto it. I have a strong feeling all of my fish are doomed cause of these pet store platys. I just lost one of my neons and I don't know what to do
