How many fancy goldfish can go in 10 gallons?

Just wanted to know.

 

i had 5 when i had my 10 gallon FW but I ended with 3 big ones

 

The general rule with FW is, 1 inch of fish per gallon of water.

 

Anyone else?

 

Depends of the methoed and type of filtration and the species of goldfish.

 

are you planning to breed? Do you have any SW tanks

 

depending upon filtration you could do more, but when its full grown id say 1.

 

Good call, a lot of people don't realize that goldfish can get very big, about 7" depending on the type. I would say you could have several small ones, but as they grow they will need more space.

 

I typically recommend 2.5 gallons of water per 1" of goldfish body. This keeps your nitrate levels in check. If you're overstocked; perform small, but frequent water changes; instead of the typical weekly changes. Always reduce nitrate levels gradually to keep from injuring the fish.

Nitrates are often confused with toxins similar to ammonia or nitrite, but this is not the case. High nitrate levels create dangerous water conditions by oxidizing the iron atoms in hemoglobin, and by reducing oxygen supply to the blood stream and tissue. This condition is called Methemoglobinemia; closely related to the effects of DCS.

Two or more of the following symptoms may be associated with nitrate poisoning, the third and final conversion of the nitrogen cycle; loss of appetite; bottom sitting; bent positioning; curled positioning; crooked spine; swimming in circles; uncontrolled swimming; raised scales or pine coning; spasms or twitching



Feed fish more often in lesser amounts so that nitrates are being produced consistently.
