r/glofish

I had fun taking some close up photos of the Glos today 🥰

We had glofish for years without issues. Then we bought a 10 gal tank. Bought a few more tetras (all tetras). My daughter decided to do a water change herself and added rocks (store bought) but forgot to rince them. They all died...except one. I did 4 partial (25%) water changes over a week and half. Then bought 4 more glofish yesterday. They all died overnight except for 1. So i have 2 fish left now, including our original one. What are we doing wrong?

This fish was a rescue, someone was housing the tetras with a catfish and this one specifically had been half eaten by the catfish the day of rehoming. Not sure if maybe that has something to do with the way it is swimming but anything I can do for it? It looks like it’s struggling to swim to the bottom and can’t stop from floating up. Started right after today’s feeding.

Got my plants today and finally finished the decor.
