Goldfish Question

[BorderColliez]

Hi, sorry to get off topic, but a 10 gallon tank is not big enough for a goldfish. All goldfish grow up to 8 inches unless stunted in a small tank which causes lots of pain for the fish

GOODNESS I can't belive your golddish eats other fish! That's crazy--never heard of that before! I've seen GF in with goldfish 10 x their size like Kalei said! They're usually sweet fish! I'd just leave him alone and let him have his 'own' tank for himself, because obviously that's what he wants. I'm sorry about the other fish that he killed

I've heard of this, but I always find some other reason for the "aggression". Since goldfish aren't a species that interacts much socially, they don't show what can be considered true aggression. Chasing and nipping can be because of sickly fish (I always quarentine for 2 months) or from breeding behavior. Goldfish will also swallow any fish small enough (they are opportunistic feeders). That's one reason you shouldn't put small sucker fish or algae eaters with them, they can die getting them stuck in their throat. A 10 gallon is too small to house a goldfish. I suggest just keeping your fish seperate because he eats other fish, not because he's aggressive.

Yep, 10 gallon is too small.

My goldfish would also eat any small fish that they could fit in their mouth. They also almost ate an African Dwarf frog that I put in there. Luckily I saw this and was able to remove it and place it in a different tank immediatly.

how big of a tank would you recommend for one goldfish?

just wondering

he is just a plain, non fancy goldfish.

was just doing some reading (google) and 10-15 gal per goldfish is recommended on every site that came up.

For a single-tail, 15 gallons per 3 inches of fish is good.
