It's not uncommon for goldfish to hang around each other in a tank; sometimes they don't bother with each other, and other times they are bumping into each other.
goldfish are not always one color because they have different species. Also, goldfish can change colors over time. They won't always be gold or maybe they won't always be white or whatever color your goldfish is.
Intrusion..!
Goldfish do not get pregnant.
Many colors. I had two male goldfish. One was white and the other one was red.
My two goldfish were in a tanktogether and mysteriously one died.i blame the other one named nemo.it killed dorie
Because of their bright, golden color. One of their other names is "Golden Carp".
One goldfish chasing (or in this case biting) another fishes rear is how goldfish flirt, however this could also be a display of aggression towards the other fish.
I had several small tadpoles in a tank- each less than 1/2 ich long. I added 2 goldfish who promptly ate all the tadpoles. One goldfish died, the other thrived. I suspect the one goldfish died from overeating but I can't rule out parasites, bacteria or other problems from the tadpoles although I would have expected the other to get ill as well. I guess the one certain thing is that if you like the tadpoles, don't add goldfish. S.
They were probably fighting with each other.
"the frog eats the goldfish, unless the fish are too big for it's mouth. " -unknown Yes the goldfish will get along with him once they know what he is. And he will get along with them. I have one and the goldfish are tiny and some are big and he leaves them all alone. Ive had frogs for years with many kind of fish that are small and he always outgrew them and leaved them alone. But in other circomstances maby not. - aaron!
NO!
Goldfish need water to swim and breath in, not mud. There are some species of fish that have evolved to survive in mud but Goldfish are not one of those species.
