Pretty fish, is that a bubble eye?
I had one and it got caught in my hose when I was siphoning the tank. I tore it in half getting it out. I'll never get another one. I was very upset. I had tried hooking up the hose and turned on the water but that fish was Stuck.
The same thing happened to the woman I work with and she is very experienced with gold fish so be careful when you siphon the tank.
