Black Goldfish. I haven’t got the patience to try and get a better grab. It’s in a way inadequate environment though, considering how big Carp get. People never realise that they grow up big. And there’s no air pump or filtration. Dis fishie gonna die.
It’s a ghost fishie now. No reason why this one should join it. basic upshot is that a bowl starves a fish of oxygen which is why they don’t really get big, but it is a carp and needs more oxygen. so a tank with an air pump is the humane answer.
Let me just add that I’m not accusing them of cruelty. Just pointing out that the likelihood is that the fish won’t last long in its present home. Honest ignorance aint no crime.
