Goldfish Maintainence-fish/tank size
« on: March 29, 2013, 10:20:05 AM »

The person at meijer told me that the comet goldfish will only grow as much as I allow them to. Naturally they're supposed to grow up to 14", and I heard the exact opposite from petsmart or petco, they told me that this was inaccurate and the goldfish will grow to full size no matter what.  Huh I had already bought 6 goldfish and theyre all together in one 10 gallon tank. 1 died just several days later but my other 5 are completely fine. All of them are at least 2 inches but not over 3. I read that one 2" goldfish should have 10 gallons/fish and I'm wondering if this is an over exaggeration?...if thats so, how big should the tank be when it grows to 12"-14" to live happily? I havent noticed them fighting each other at all or acting scared. Sometimes theyre really still, and other times theyre swimming aroung not rapidly but non-stop like theyre looking for something...they act hungry when theyre not, i guess thats normal for them. I realize I should take at least 3 of them back and tell them that the attendant mislead me, I believe that 2 comets should be fine in 10 gallons. I can't believe how many comets they have crammed in their tanks at meijers, theres at least 70 or so in just one 15-20 gallon tank, that cant be healthy.  Undecided

I'm afraid your tank is terribly over stocked realistically a goldfish should be in a pond. They will continue to grow but will become stunted if you keep them in the tank you currently have them in and this will lead to health issues and death. I had a comet and a shubunkin in a 180L tank and still had to rehome them as the tank was too small. Some pet shops won't take fish back you could try but even if you did they would still be cramped in a tank that size. Goldfish are from the carp family as are comets and they grow to 2 foot in length, therefore they need a tank to withstand that size and give them room to swimm happily without banging into the sides.
When a fish is stunted it makes them week and susceptible to illness I lost a fish from stunting and I know there are some people on here that have their own stories to tell.
The first shop you went to was wrong and it sounds to me like they just wanted to make a sale.

A goldfish's skeleton will quit growing in a tank that is too small, but the internal organs will continue to grow, eventually leading to death.

Thanks for all of the information. I returned 3 of them  Cry So now I'm down to 2 of them in the 10 gallon tank. I believe its fine for now but definately will upgrade in the near future, just have to save some money and wait til we move to our house so we have more room. I assume my filter cartridges will last longer now with 2/5 of the waste  Grin

They should be ok for now. You may find that when you do upgrade they won't grow as quickly as normal but that's not too big a problem at least you are doing your best and listening to advice. Good luck with them and enjoy them. Any problems just ask us.

Glad to see everyone gave awesome advice, but I'd like to mention one thing, AZriverrat you're information is wrong. When a goldfish becomes stunted, yes their growth physically stops, but so do their organs. It is a complete myth that the organs continue to grow.

As for your situation Dara, I can completely relate.

I have a single tailed goldfish on her own, she was originally in a 5 gallon tank (with Star who we sadly lost) and about a year ago I upgraded her to a 3 foot/23 gallon tank. Her growth is very slow and so I'm keeping her for now until she is big enough, then I will be re-homing her to a pond or organising a larger tank.

Ultimately single tailed goldfish need to end up in a pond or a really large tank (at least 6 foot in length) but I can appreciate this isn't possible for everyone -myself included, so I've been considering re-homing and will find my little goldfish a pond when she's big enough. Or if her growth is really bad, I will look into building or purchasing a larger home for her.

You need to think what's best for you as well as the fish, may I ask how long it will be until you move? Simply because the longer those fish are in that small tank the worse it will be, Lucky was only in her small tank for 5 or 6 months and her growth has been massively affected from what we might think is a relatively short time.

Have you considered getting a large plastic storage container in the mean time? I have seen plenty of people use them as temporary accommodation, as long as the item in question is food safe and can handle holding the water, it would be fine Smiley

Can I also ask how the goldfish behaviour is with the remaining goldfish? You will want to keep up maintenance as the tank is more than likely cycling, so I would suggest doing large water changes weekly, take out as much water as you can (around 80% should do it) and always use conditioner for water that you're putting back in. This will at least keep the water quality good, until you can get something bigger.

It would also be worth getting a pet store or buying a kit to test your water quality, you'll want to keep an eye on it, because if one of the bad elements i.e. ammonia, nitirite or nitrate, spike you will need to know about it and be able to re act accordingly -generally just 50% water changes daily until the value is back to 0ppm or in the case of Nitrates under 40ppm.

If you have any questions feel free to ask, I hope what I've written makes sense!
