Best buddies
Well, the attempt to re-unite Lilly with her buddies failed, they are still in a way too small tank in Amsterdam. But doing OK and provided with a lot of attention, proper water and feeding regimes, and lots of people peering in and saying Hello.
Lilly, on the other hand, certainly enjoys her new home. But was obviously bored, spending huge amounts of time swimming end-to-end and not interacting with the tank at all. So I have put my two little Ryukin goldfish into her tank. So far so good, she certainly seems more stimulated and engaged with the tank, her new buddies and the eternal competition for food
You are not really supposed to mix Comet goldfish (like Lilly) with fancy species, but all the time they are getting on OK and nobody is chewing the others fins I’ll leave them together. I think the incompatibilities really come to the fore when the fish are crowded and food is scarce.
