Fish problems

Subject: Fish problems

I have a Biorb life 60l. Been set up since January. Water tested locally at reliable fish place and all in order. Tank came as a kit with pump and ceramic stuff. Have added only Biorb plants and. £50 feature. 50% water ch@ng3d with tap water treatment 10 days ago. Only have goldfish. 2 died in last week. 6 small and one about 2” left. All top fins flat. Feeding well and active but as fins down doesn’t look right. Changed filter and carbon 3 days ago washed in tank water. Any advice please. Bill
