Does this mean that next winter she will need a heater or her bb will cark it and every spring the poor fish will have to go through a nitrogen cycle unless she gets a heater for it in winter?
Its also hard growing aquatic plants with goldfish, although I've found a few mine won't eat, I can't say the same for the two in the pond..
I guess I could try telling her to experiment with them and find out what they eat and what they don't, so on and so forth. She's taken quite the attachment to the two fish (previously named Bubbles and Star
poor fish) so I might just be able to get her to buy them some plants.
I have some duckweed growing in a tiny tank on my window ledge that I'm planning to take around to her when its covered with a nice layer of healthy duckweed... But I doubt that would last long, especially since they've been eating flakes their entire lives.
I'll probably just end up taking the entire tank around for her to put somewhere sunny so then her goldfish can have a yummy snack here and there.
