We are going away in 2 days on holiday and I started to fear that it would die while we are away and then contaminate the tank but I have had an idea. I remembered I had some aquarium salts in my maintenance cupboard. I also remembered about my vacant 60L tank which I have been running and maintaining since the previous occupants died around a month ago. So I have put some salts in it and added the Angel. That way, if it dies while I'm away it shouldnt affect the other fish. Probably a silly question to some, but if a fish has no partner to make it pregnant can it become egg bound? Are they like chickens that still lay eggs if if they are unfertilised? I have only ever had live-bearers before, I acquired the angel when I bought a tank about 2 years ago
