I have had this aquarium for about ten years but have never seen this problem before. I am losing fish slowly. the first a golden groumi looked like it had a raw spot on a side, the next a blue groumi looked fine one night and the next morning was gone and looked like it had bruises. I now have a black skirt tetra that looks like it has a growth on the mouth, and is acting sick. I don't expect it to last until morning. Anyone have any ideas I do regular partial water changes, have some new artificial plants. ??

Welcome to Fishlore. Hope we can help you out.

I'd recommend the API freshwater master test kit to get your water parameters.

If you can get Fish Protector or Vita-Chem, they could help with whatever problem is going on. Rid-Fungus would be something that I'd add as my first thought is a fungus perhaps. Do you have a picture to post?
