jamal Posted September 29, 2009 Report Share Posted September 29, 2009 Hi all! Over the past few months i have been trying to find out the minimum stocking levels for a pond containing one comet goldfish and one common GF. This may sound easy to find out, but i have got many mixed answers ranging from 40 liters to 400 liters! (fortunately i am not so gullable to believe 40L is correc!) i was thinking maybe that 220L would be OK, but im not sure. So, on the subject of my two GF, i have a VERY unusual fish. She is a GF i guess, but she has scales on her sides and top which are the kind of large metallic scales you would find on a Doitsu Koi. She is also very deep bodied and has a MASSIVE mouth which anything that falls in my pond, and frequently chokes on large slugs which i have to pull out with tweezers. She is also extremely bold and afraid of nothing (i have been told that is a koi characteristic) whereas my other GF is qiute shy. I have researched GFxKoi and she does not match either. Do you know what she is? Any help is appreciated, thanks! Link to comment Share on other sites More sharing options...
pilchard Posted September 29, 2009 Report Share Posted September 29, 2009 Are you sure your not looking for the maximum, the minimum is 0, you dont need to stock an outside pond. youll get frogs and stuff with no fish in it. if it is an outside pond what are the maX summer temps this pond reaches. if indoors 230Litres is a standard 5 foot tank so with good filtration you could run say 20+ GF, with good filtration and weekly water changes of 30%, you could even breed them in this size if you took the stock levels down to under 10. Does this pond/tank have filtration?? is it in full sum, or shade?? stocking levels really depend on the situation and not the size, we need more info as to waterchange schedules and size of inhabitance and so on. Are there live plants if so what are they and how long have they been in there. Also the strange GF is a pearl scale... Link to comment Share on other sites More sharing options...
Marianne Posted September 30, 2009 Report Share Posted September 30, 2009 Goldfish get huge, up to 30 cm, so they need big tanks. I always say a minimum of 200 litres for one goldfish, so I guess 250-300 would be suitable for two. There is no way you could keep 20+ goldfish in a 230 litre tank. Maybe when they are small, but they need room to move, not to mention they are extremely messy fish and you'd need a massive filter for that amount of goldfish in a fairly small tank.

pilchard Posted September 30, 2009 Report Share Posted September 30, 2009 Iv kept goldfish for 15 years in tanks this size and spawned them... and as stated stock levels were reduced when initiating spawning. i also believe gf growth rates are relative to their environment more so than in other species. so your saying that only 2 30cm fish can be kept in tanks of 200 litres, you better tell the cichlid nuts there all doing something wrong then. iv sucessfuly kept and spawned oscars in a 230L and kept 4 adult male fish in the same amount of water, without any dramas, and these guys must be one of the messiest fish going.

KenR60 Posted September 30, 2009 Report Share Posted September 30, 2009 As mentioned there are so many things to think of, Filtration If the Pond isn't Filtered and lots of oxygen available then expect to loose fish if you over populate the pond. Plants are important as they help to also filter the water and give the fish both hiding places and oxygen. Pond Volume The larger the pond combined with plenty of food will allow larger and faster growth. I added around 70 normal 50-60mm Comets and Fancy Goldfish and a year later some are approaching 300mm in length. If you Google "Water Area per goldfish" you will get some recomendations and everyone has their own theory but remember, if you want them to grow bigger then stock less.

jamal Posted October 1, 2009 Author Report Share Posted October 1, 2009 Japelno here! Thanks everyone for all your answers, you've really helped. But i don't think my strange GF is a pearlscale, shes long and thin, anyway if anyone has any more suggastions, i'm happy to hear them. Thanks!

Marianne Posted October 3, 2009 Report Share Posted October 3, 2009 I don't believe in cramming the most amount of fish into the tiniest tank possible, I believe in trying to give my fish a natural environment where they will be happy and thrive and grow as big as nature intended.

Yes Agree Marianne, this is the Best method and thats why I've gotten my 70 Goldfish to grow so well in such a short period. Space and Food combined give Size :-) Their Pond is 11 metres long and 2.4metres Wide at the widest point ( 8,000 litres ) As soon as they see me walk out on the Deck they swim like crazy up to where I am standing and actually follow me anywhere I walk At the moment I have hundreds of fry swimming around and they are still breeding each morning.

jamal Posted October 9, 2009 Author Report Share Posted October 9, 2009 yes, i want to give my two goldfish the best. so far, the only larger home for them is 220L and that will take a few months to aquire. i'm doing everything i can for them. do you think i should give them up? they are in a very small home, however, they are both really healthy and in a very clean environment. is it worth keeping my goldfish if the very best i can do is 220l? i don't know anyone who would take them or anyone who i would trust with them. i really do not want to give them to a pet store. around where i live they are extremely incompetent. so should i keep them in 220l? or give them away? thanks, japelno Link to comment Share on other sites More sharing options...
jamal Posted October 10, 2009 Author Report Share Posted October 10, 2009 just wanted to add that giving them away would crush me. :lol: Link to comment Share on other sites More sharing options...
