hiya i am just wondering for a goldfish what plants are suitable, and which snails, and how many snails would be advised? for a 10g tank how many gold fish? 1, 2? sorry about all these stupid questions, im not experienced in goldfish, only tropical. any other tips feel free to say, thanks!

as far as goldfish are concerned im pretty sure they wont mind any plant you put in with them, you could do mystery snails, they need a male and female to mate so if you only have one you wont have to worry about a population explosion and i believe i've read somewhere that you can put a snail in for every 2.5g of water but dont quote me on that and i personally wouldnt put that many in a tank, as far as how many goldfish i would honestly say none..,a ten gallon is still realitivly small as most fancy goldfish can get to 8"-10" a 20 or 30 gallon would be alot better choice

A 30 gallon would be to small for a fancy goldfish. A 75 gallon tank with one goldfish would be more realistic. Add 15 gallons on top of that for every goldfish. There are some small goldfish kinds but they get to be 4" which is also to small for a 10 gallon tank. Even with a grow out tank, the goldfish would have stunted growth.
This is what aqadvisor said for a standard 10 gallon tank:
Warning: Fancy Goldfish is not recommended for your tank - it may eventually outgrow your tank space, potentially reaching up to 8 inches.

Recommended temperature range: 19 - 23 C.
Recommended pH range: 6.5 - 7.5.
Recommended hardness range: 5 - 15 dH.
Recommended water change schedule: 44% per week.
Your aquarium stocking level is 129%.

Comet goldfish are even worse. They get to be 10 inches big. Ryukin goldfish get 8 inches. A typical goldfish might even reach 12 inches. Orandas get to be 8 inches. Fantails get to be 8 inches. Black Moors: 10 inches. Crown Pearlscales: 8 inches. The smallest goldfish is the Siamese Doll. It gets to be 6-8 inches if not bigger.
Not to scare you... but goldfish get BIG.

75g for one gold fish is a bit over kill, but yes, larger is better.

Each goldfish needs 30g at least and then an extra 10g added for every goldfish after that. So, for 2 goldfish, you'd need a minimum size of 40g, but bigger is always better. Why get the bare minimum right - you want them to be healthy and happy... so go for 2 in a 55g maybe.

Goldfish are super messy fish and require double filtration... so on a 55g tank, you'd need enough filtration for an 110g tank, and you still have to do large partial water changes weekly.

Upside is they are cold water fish so you don't need a heater.

If you put a gold fish in a 10g tank, it's skeleton will become stunted, so it will stop growing on the outside, but it's organs will continue to grow. So basically, the fish ends up dying a very painful death when it's insides explode.

Aqua Advisor is a great resource but it is just a guide line, so when using it, also use common sense. And, the 1" of fish per gallon rule is complete garbage! Once you account for the space used up by gravel, plants, decorations plus the heater/filter intakes and all that, there is waaaay less room than there was originally. It's always best to stock the tank at about 70-80% maximum and have healthy fish, rather than stocking it 100%+ and having fish die all over the place.

Before adding any fish, research the Nitrogen Cycle. You need to put your tank through this in order to be able to keep healthy fish. Fishless cycling is nice, because it doesn't risk the lives of any fish, and is often a little faster than cycling with fish.

To answer your original question though:

Snails: Most snails sold in stores are for warm tropical tanks. Sometimes Apple snails are sold as "compatible gold fish tank mates" but they actually need warmer water, plus the goldies will eat their antennae and eye stalks. You can keep Pond Snails and Rams Horn Snails with goldies.... they are considered pest snails though, and if you over feed your fish, the snails will explode in population. If you find you do have too many snails, you can create a snail trap out of a water bottle, or put a piece of zucchini in the tank at night then take it out (with all the snails that are on it) in the morning, or just pick them off the glass and toss them. They are great algae eaters though. (Snails also need a pH of over 7 or their shells will erode and they will die.)
Fish: White Cloud Mountain Minnows can be with gold fish I believe IF and only IF you have a big enough tank (over 55g's), as the minnows need to be in groups of 6+.
Plants: As for plants... gold fish tend to eat and up root most of them. You can, however, try some Java Fern and Anubias plants, as goldies tend to not like the taste of those, and since you need to anchor those 2 plants to rocks or wood, they can't be uprooted. You could try some Hornwort and let it float. The goldies may nibble on it, but it's a fast grower, so it should be able to keep up with the fish. Duck Weed (floating plant) will be eaten quickly by goldfish and you can give it to them as a snack. Java Fern and Anubias can live in low light tanks, but you still need to make sure that the light is suitable for growing plants. (For example, "Life Glo" bulbs are for aquatic plants and can be found in many fish stores.)

You can take a 55g tank and make it look fantastic with Java Ferns and Anubias on rocks and wood, with a little floating hornwort, some rock caves, the right lighting, and 1-2 goldfish. A really pretty centerpiece for any room.

I am talking about a full grown, non-stunted goldfish. It does sound like overkill but goldfish get big. Most people say a common pleco should be in a 125 gallon tank, no less. A full grown goldfish is a little smaller than half a full grown pleco. So a 75 gallon tank would be about right. Goldfish also produce a ton of waste so there is another reason for a 75 gallon.
And finally:
Happy Birthday holly12!

Lol, thanks for the B-day wishes.

Yeah, full grown goldies get big.... great pond fish indeed! Could probably get away with a 55g for a few years before a 75g is needed. But double filtration for sure, cause they are super messy fish!

As pretty as goldies are, I don't usually recommend them as "aquarium fish" since they need more than what most people want to provide.

I am with holly on this one. 75 gallon is overkill for one goldfish, imo. One goldfish will have plenty of room to swim in a 30 gallon tank. Their growth won't be stunted. A standard 30 gallon tank is 36" long. If most goldfish get to be around 8" - 10" you still give them 24" - 26" of space to swim around and in an aquarium setting that is a good amount. Of course bigger is always better and as long as you throw on double filtration and do weekly water changes it shouldn't be difficult to take care of.

When I put a Fancy Goldfish into aqadvisor it said that my theoretical 30 gallon tank is 55% stocked and required a 15% weekly water change. There were no other warnings. Most discussions that pop up on the subject of goldfish will say similar results.

You have to consider that if its a comet goldfish, which will reach a foot, will need at least 75 gal but you can have more than one in there. Not that many more and would be best in a pond. A fancy goldfish and will do good in a 30 gal. +10 for each additional goldy.
Goldies are known to eat plants so you must be careful in your choice of plants. They will also eat snail. If you look in petco and you see a goldfish in a tropical tank, They are in there to eradicate the snails.

I'm currently doing up a goldy tank to house some fancies

40gal tank and it will house 3/4 at the most. It will be running a canister filter and will be getting weekly water changes.

About the snails - my advice is to never have snails wth goldfish. I accidentally got eggs from plants I bought that were stocked with mystery snails. I had one snail only, until it began to lay eggs. Snails are asexual, and do not need a mate if they dot have on present, though they do mate if there are. I ad a complete infestation, and finally got it under control after a year. they make more poop than goldfish, which is saying a lot, so if you don't want to ave to clean your tank every two days, don't get snails. Dont do that to yourself, it's a nightmare!

mystery snails actually arnt asexual, you need both male and female for them to multiply..

^ indeed! Out of 6 Mystery snails I think I have 1 male, lol! He is forever climbing all over the other snails and trying get under their shells! XD First time eggs the other day, but they dried out before I found them. :(

there is a lot of debate about that, so i respect that. but from my experience, with having one snail for many many months, then suddenly having hundreds - literally hundreds - i would say they are asexual. but, again there is a lot of debate.

While there may be a lot of debate on the topic mystery/apple snails are not asexual. There needs to be a male and a female for them to breed.

Yep definately need male and female mysteries to get baby mysteries. Lone females may still lay eggs but not fertile.
No debate needed on that its fact
