Do fish grow fast in a smaller tank?

[DeLgAdO]

Hi,
I was wondering if fish grow faster in a smaller tank, i have 2 x 3" juvi tem pbass, and they are in my 60g at the mo, but i was wondering if i put them in a 10g by them selves and did a 20% water change every week and feed them daily on bloodworms if they would grow fast? then i can move them into my 60g again and then in my 120g once they hit about 6". What are your thoughts on this? Thanks

they grow the same rate be it a big or small tank

the reason small tank would stunt a fish growth would be because of poor water quality and health management.

a large fish can foul a small volume of water very quickly, these wastes then cause stress and or disturb the fishes normal body functions.

think about that 34'' aro that grew its life in a 75 gallon tank

and look at my aro and rallymans aro which are in double and triple that size tank and our are barely over 2 ft, go figure

I tried looking for the article but I couldn't find it. I think it was a Jack Wattley article (I know this isn't about discus but just read) in TFH. Him or a fellow discus breeder conducted an experiment that had a few groups of discus that they put in small and large tanks. The only difference besides the tank size was the WC schedule. In the small tanks, almost 100% of the water was changed every day and the bigger tanks got a less strict schedule(but still up to code for most hobbyist). The fish in the small tank grew a lot faster than the ones in the large tank(and from my understanding- these fish in the small tank were CRAMPED!) Feeding was also the same for both tanks. There was also mention in this article about a similar experiment except it used oscars as the subject instead of discus. This test ended with similar results.

If I can find the article I will list the date of the mag, and you can read it for yourself.

yes! read that article...pretty good and informative

Good, I was starting to think I made it up. Do you remember what mag/issue it was?

I think if you keep up on water changes (like 50%-75% once a week) and feed them a lot, they will grow fast no matter what. I once had a Clown Knife that I was growing out in a 10g. I got him at 3" and it grew to 11" in about 6 months (I didn't get a chance to get a bigger tank yet). But I think the more space you give them, the faster they will grow, and the better it is for them. It gives them more excerise and the water won't go bad as quickly.
