Any advice or credible websites on raising goldfish?

It’s called a Black Moor.

I’m a little confused by your phrasing: are you looking for information on breeding goldfish or for information on goldfish husbandry?

Goldfish are one of the easiest fish to keep (except perhaps for bettas), although they are know for being quite dirty. I’ve never researched it, but I was under the impression that ponds/larger tanks are required for breeding. What exactly happened with the bettas?

I breed fish, so this is easy.

Goldfish don’t keep well with other fish because they produce excess nitrogen (i think nitrogen… excess something or other).

If you’re purely aiming to keep it alive, just go buy a regular goldfish. If you can find an already grown one get that one (sometimes they’re called “comets” when they’re big… it’s still a goldfish), as they have a fairly high mortality rate from their youth (aka feeder fish). Don’t get a fancy one, they get sick way easier ESPECIALLY the bubble eyed ones.

Other than that, just keep the water temp between 60–75, and feed once a day a pinch or so. Far easier to keep than a beta (though in fairness, betas are pretty easy to keep too).

@syz The latter. It would be cruel for me to breed fish since I can barley keep one alive.

Don’t over feed them! Apparently the rumor is that they only have a three second memory so they will have forgotten that they have already eaten.
