do you think fish growth is reduced by tank size

[nomadofthehills]

I raised a GT from .5 to 6"+ in one year in a 10g. I did 2-4 90% water changes a week. He now lives in his 55, which gets a 90% water change every 5-9 days. He was fed krill, shrimp, Omega ONE, and earthworms.

His growth was not stunted. One must realize that wild fish can live a long time. Those monster wild fish are likely 10+, 20+, maybe even 30+ years old.

Water quality and diet are key.

I disagree!!! Say you have a oscar in a 10 gal and he only gets say 6 inches before he dies (of unknown causes) more then likely the fish didnt have stunted growth it was short lived because not having enough room to grow and move around like it was ment to..

Just my opinion

also remember arrows in the wild often die due to lack of water and oxygen in the dry season, the ones who live are lucky enough to be in a deep pond when the water recedes. Arrows the size of some that people call monsters in their tanks laying in puddles dead... There are benefits to the setup, some may not survive in the wild...imagine how old most of the bigs must be...

The Amazon river is in a tropical rain forrest, there is no dry season. Not sure where the aros in puddles info is from? Does the amazon river have flood plains as you would find on the nile river in africa?

From http://library.thinkquest.org/21395/textonlyb/climate.html
In the Amazon region, there are basically two seasons: a rainy season and a not-so-rainy season. In the rainy seasons, one can expect up to 60-180 inches. In the "dry" season, one can expect anywhere from 30 inches to 100 inches.

What about Africa and OZ?

No it probably died of high ammonia/nitrates.. A 6" oscar would have room to turn around and maneuver in a 10g. Stunting wouldn't be the cause of death IMO. A fish would die of poor water quality long before it would die from being in too small of a tank. I mean in extreme cases if you put an arow in a 10g then the fish may stunt, harm internal organs and die but we're talking fish longer than the tank is long.

problem, during the time of the studies am I wrong to remember that under gravel filters were all the rage...instead of removing waste we were leaving it in... any connection?

Water changes are the key. And they are more key to growth than tank size. Look at asian themed tanks, yes some buy their fish big. But they also grow some of the largest fish of their species because of water quality. Someone over there even grew a 21" P. Dovii in a 4'x2' tank.. why? It was on drip..

There is a dry season in South America.. that paragraph doesn't speak of it but I've seen it in documentrys where lakes/small bodies of water dry up and fish become camien/bird food. Specifically I saw it on "Piranha: Wolf in the Water" but I would imagine it being South America other fish are affected too.

There is definitely a dry season in the Amazon Rainforest haha!

At some public aquaria, if they were to live near the sea, they can have huge pumps that pump water out from the main display and into the sea, whilst another pump brings fresh seawater into the display. The result is very clean water.

there is a dry season... part of the year the entire area is flooded... and fish swim all over the flood plains... In the dry season many fish die due to lack of oxygen or dry out... It was HD the other day... Dry season does not mean dessert...
