i'm new to the cold water thing and i'm just playing with the idea at the moment. i just read that a black moor goldfish gets to about 10cm(4in) and the fantails get to about 15cm (6in) is that right? what sort of tank size would they need (together and/or seperately)?

i also read that people keeping the little guys in small tanks are stunting their growth... would the goldfish still reach sexual maturity if it stayed small? would it still be happy... just tiny? or would it be sickly and stressed?

whats the smallest type of goldfish? i think the fantails and black moors are cute but i don't have room for another big tank. would either one go in a 10 gallon happily?

Hi There,

Black Moors and Fancy Fantail Goldies all reach a good 8+ inches or bigger, provided they are given the right food, water quality is good and are given enough tank space to grow.
IMHO any goldfish should not be kept in a 10 gallon tank or smaller period. Ideally the first goldfish needs 20 gallons and then each additional fish you add needs 10-15 gallons.
Goldfish are large, dirty fish meaning they produce an amazing amount of poop! LoL :o The more you feed them, the more waste they will produce.
Good Luck and let us know if you have any other questions!! :hi:

When you guys say that "the first goldfish needs 20 gallons", does that mean that 20 gallons can only support one goldfish, and one goldfish alone? Or can there be companion fish in the 20 as well?

Depends on the companion :) Most of the cold water fishes that are suitable for tanks are schoolers or groupers. I wouldn't put anything in the middle water column at all.

An apple snail or two works, but keep an eye on it. If they die, they will pollute the water BIG TIME and with goldfish, that can really negatively affect them. I had a Mystery croak in my son's temporary 20g oranda tank. Snails often close themselves up for a day or so and not move, so it was two days before I pulled it out of the tank to see if it was alive. It must have died immediately after closing because there was a huge ammonia and nitrite spike when I tested the water and I had just changed and tested it a few days beforehand.

You could probably do one dojo, providing there are lots of places for it to hide.

Anything else and I'd recommend a bigger tank. The two goldies in my son's tank are either going in the 36g I have here, or a 40-50g. Gonna try fully planting (with rocks on the roots to keep the goldies from digging them up) and a couple of dojos to make things interesting :)

Just gotta find a place to put the tank. This is supposed to be my STUDIO and now it's fully of fish tanks :rolleyes:
