i need some advice please
 
Hi all,

i've had my freshwater aquarium on the go since august, ive got some common golfish and i was after some advice on adding some orandas.

i was just wondering if the mix well because so far i have had conflicting advice on them so far.

please help

orandas are technicly goldfish,they have just ondergone years of selective breeding to create the typical oranda form, they can be outcompeted for food by goldfish as they are strong ,boisterous fish which is lacking in the dumpy oranda but as long as everythings seen to be getting its share i dont see the problem one of my relatives has orandas in an outside pond alongside full grown carp and koi and they are doing very well

how big is the tank?

hi the tank is 6.6 gallons.

i decided to get one and it seems to be doing so far so fingers crossed.

you will at some stage have to upgrade this tank to something larger goldfish can grow over 12 inchs long and weigh up to 8lbs orandas are actully a better choice for an aqarium as they can cope with less space than commons due to there shape,another thing you may want to keep an eye on is water quality goldfish are very messy and overfiltration is preferable as is water changes which is very important in smaller tanks

Yikes! I would get them into a bigger tank as soon as possible. Keeping them in a tank that small severely stunts their growth which can lead to health problems later in life. The fancy goldfish can get up to 12" in optimum conditions though 8" is fairly common. The comets can reach up to 18" with a foot being quite common. I would say you would need at least a 90 gallon tank to keep common goldfish long-term.

Generally each goldfish needs it's own ten gallons of water. 2 goldfish need twenty gallons, 3 need thirty and so forth. 1 Goldfish does not fit into a tank smaller than 10 gallons, because it produces a ton of waste and needs the room to swim. Eventually, in a small tank, the fish will produce more waste then you can keep the water clean and will sufficate.
