Hi Cheryl.
I'm very glad to hear that Goldie is doing better but I'm still concerned about his "jump".
If you get a Master Test Kit you'd be doing both yourself and Goldie the world of good. It takes a lot of the guess work out of diagnosis as water is ususally the primary cause of a lot of fish health problems.
Has Goldie been displaying any "scratching" behaviours....maybe swimming sideways on the gravel at the bottom of the tank, rubbing off tank ornaments, yawning, spitting out food?
Parasites, a sudden PH crash or a build up of ammonia can cause a fish to attempt a "jump" out of water.
It could also have just been a freak incident!
You must be a great fish mommy to have Goldie for 12 yrs...congratulations. Here's to many more years with him.
