My silver aro is currently in a 5x2x2 with weekly water change quite over filtered. Now I realize that an ideal tank size would be Around 8x3x2 but other then it having more room there wouldnt b any difference in water quality so it wouldnt hurt the fish any more or less surely

Wow great arguements since the last time I looked, glad we went away from dolphins and whale sharks lol.

One point I havnt see yet is full potential. What is an animals full potential? Many people look at record sized fish and say that is how big it is supposed to grow. In reality, records are just that, records. Rare sizes that have been found with the average full potential for an individual might be half that size. There are some humans that have grown over 7 feet tall, is that our full potential for growth if properly cared for? If so, I have a fight to pick with my parents. I love bullheads and I know how big they usually get if properly cared for. I have also seen record fish more than double what a bullhead would normally get in the wild or in an aquarium. I would NOT use that arguement to justify keeping an aro, saying it usually only gets 3 feet. But fish smaller than full potential are not necessarily stunted or unhealthy. I would say thoroughly research average size from people who keep them in decent set ups and be prepared to do something if your fish gets past the average(obviously your fish is going to full potential). Just because someone with a 10,000 gallon tank has huge pbass does not mean all other pbass are stunted or unhealthy. Do not apply this to all species and do not use it to justify keeping monsters like pimas. I do think average size of healthy adults can help establish bare minimum.

Another example is moontanman and his runt paddlefish. If you havnt seen his thread look it up. He has a plan for if the fish get larger than expected, but his fish are genetic runts that are not expected to surpass 18-24", far from full potential and are healthy and not stunted from improper care
 
You win and your fish win.



I am guilty too. We all are to a certain extent.



Who is upset? I thought we were having a healthy debate and if what you say were true, there wouldn't be so many "look at my RTC, Pima, GATF, Aro, Bass threads."

Keep us posted on your RTC in your 125G tank. I'm curious to hear how that works out.

Actually he is going to be doing good he is going into a 180 I bought brand new with stand combo. I brought back the 125 since they gave me a deal on that setup.

I don't care if this tank has perfect water parameters. It is equivalent to keeping a German Shepard tied to a stake in one spot with a 3' chain its entire life. IMO it's wrong to keep fish this way....but that's all it is .... my opinion. There is still some unoccupied space in this tank. The tank owner should add 25 - 30 more oscars and other fish to the tank until none of the fish can turn around. That would then be a fair situation to all the fish. There will probably be some people who will view this picture and be inspired to do the same thing. Other people will be horrified.

This thread has put a lot of people on the defensive. Some have even tried to turn it into a battle of the haves against the have nots. I don't think that was the OP's intention when starting this thread. Put me in the "have not" group. I will never have a tank big enough to house a arapaima, so I will never own a arapaima.

I don't see how you can't understand this. It's easy to draw the connection. Look at south American fishing forums. If you look at sizes and pictures of peacock bass caught in the wild, they're huge. Then you see the size of peacock bass in captivity that are kept in monster tanks; they're huge also. Then you look at the size of peacock bass in captivity in small tanks (200-400g) and they're small. How difficult is it to draw a conclusion from this? It's common sense, not rocket science.

And please don't use the term 'unhealthy'. We're not talking about that. We're talking about stunting and physical size capabilities. But I can also play that game. Just because a fish is healthy doesn't mean it isn't stunted :)

People tend to show monster specimens in fishing pictures...What you really need is a study in size distribution in wild populations.
 
There's also the opposite end of the spectrum. This debate doesn't only apply to monster-sized fish. You can do this with any sized fish. Case in point:

If the water parameter is good, the only fault I can find in the above picture is a lack of hiding places for the loaches. Clowns love to hang out in groups and they like crowding...My 30+ clowns hide in one spot even though I have multiple spots for them to hide in.
