Fus passed away this morning :( I kept him in his little hospital tank by my bed because I had a feeling it was the end. He was alive when I woke up, but when I came out of the shower he was gone... I miss him already.
Now I'll have to keep a close eye on Ro. She's doing fine and I did a 75% water change this morning and added salt to just to be sure. Ammonia is at 0 and my master test kit should be here soon.
I know goldfish are companion fish, so once I know my tank is healthy and cycled, I think I'll get her a friend. I don't want her to be lonely..
And just from reading things online and talking to others who have goldfish, I still agree with fruits/veggies being part of my fish's diet along with the NLS food.
