Any fish should get as big in a display as it does in the wild. If it doesn't, you're doing it wrong. It's that simple.

Show me a clown loach that reached it's max size in the wild (16 inches) in comparison to many many others (does wurm have one that big?)
What's the largest RTC on here? I've seen many fish that are perfecly happy but don't reach their maximum size.

I say a 12-13' one seems probable, we haven't caught them all :D
 
i still stand by my answer that it doesn't matter were it is it can get that big...wonce a fish gets 5' nothing in fresh water will f with it so it can lazly swim up to what ever it wants and eat it...one ex. look at a muskie or northern pike when they get bigger they get huge guts and they are not in special fishing lakes just plain old lakes...catfish are one ex. in rivers they get huge guts also nothing special for food supply and they have to work for it in the current...yes they are diff. fish but they all are preditors so they sames rules apply

Show me a clown loach ANYWHERE that is even close to 16"?? I've heard some people claiming they'll grow that big, but I think 12" is generally accepted as the max size, I certainly haven't seen any bigger than that...

Thats a large one. Maybe 7-8 feet. but I haven't seen them outgrow 6 feet in captivity. My friend has three 5 footers.

A couple weeks ago there were over 100 members from this board that had the opportunity to see one that was clearly over 6' (sam of JohnPTC fame). I don't doubt that he will definitely reach at least 8'-9', although I imagine his growth will slow down so it remains to be seen how long that will take.

Not this again lol. If it doesn't breed, you're also doing something wrong. Welcome to the degrees of wrongness that make up fishkeeping (and keeping animals in captivity). Interesting to note, many animals (large snakes for example) get bigger on average in captivity than their wild counterparts due to constant availability of food.


You mean the truth? Sorry, like to offer that from time to time.

I never encourage people to keep animals in an area smaller than they would need in the wild. And for the record, I don't agree with a lot of the fish tanks that people keep them in.

I agree with the "larger in captivity" for a lot of species of various animals. Fish isn't one of them. I spend a LOT of time with fish in the wild and in captivity to make sure we are doing the best we can when we have them in our care.

You have failed to understand me, this is not about which of us is right or wrong.

It is absolutely the truth, you are correct about that. However, your assertion that it is somehow to noble to confine an animal to an artificial environment with no chance of fulfilling it's biological imperatives, yet grow to adult size, is wrong. Stunting a fishes growth is "wrong". Preventing it from breeding is "wrong". In fact, captivity of any organism for our own selffish amusement is "wrong" if you are concerned with what's best for the animal.

Your spacious public aquarium tanks are still prisons, not matter how lavish they seem. You are encouraging the captivity of Arapaima gigas in public aquariums, yet have the animals completed their life cycle and bred? If not, then they are not being given the space ( or chemistry, privacy, etc) that they "need". You have failed to do what is "best" for the animal.

This is not a personal attack Zoodiver, I apologize if it seems that way, but we as aquarists must understand the moral complexity of keeping captive yet undomesticated wild animals. We do this for our own personal education and amusement. Even a public aquarium keeps animals for the pleasure of the public. Yes, captive breeding programs for certain species exist, but the focus of the displays is just that, display.

Propogation is the sole purpose of all living organisms, it supercedes all other considerations, including life. Many species die in the act, or even the attempt, of breeding. If your animals are not breeding, then you are not providing what they need. This is what seperates captive from domestic animals.

We all compromise the life/health/behaviour of our fish to fit into our own lives, it is the inescapable truth of the aquarium hobby.
 
Hao,
I agree. I've never seen or heard of a 4' silver. I've seen 3'ers as much as I've seen anything. but no 4'ers.

Its more like saying silvers get to 5-6'. I've seen silvers in public aquariums that would be over 3', and I'm sure they could get close to 4', but that would be a pretty extreme case, probably equivalent to a solid 12" loach.
