leichardti questions

How big a fish gets in a home aquarium is a bit of a gray area, that is why I stated the wild size. If I told you a size in a home aquarium it would only be speculation. The size is effected by things like amount of tankmates, frequency of water changes, diet and most importantly the size of the tank. In an 8x2x2 I would estimate growth to atleast 80 cm, If you had a large tank eg 10x4x2.5 the fish will have no problem acheiving its maximum size, given that the tank isnt crowded, water changes are done regularly (to remove the hormone that causes growth to slow) and the fish gets a good diet to supply it with the required nutrients to grow properly.

Hope this answers things more fully for you.

Thanks for the reply. Though I've read many a times that fish dont grow as big as their wild counterparts nor grow as big as they would in a home aquarium. Some reasons were that they live in a vast body of water plus it contains trace elements and minerals our tap water cant provide. Thus I asked what's to be expected size-wise in the home aquarium. But thanks nonetheless

Good answers. You know your aro's.

It all depends on the keeper and how well you take care of your "baby".

From what pisce stated makes perfect sense, there is no definitive answer on how big your aro will get in your tank since there are so many varibles involved.

But suffice to say, it should be bigger than 12" in general, bigger depends on you and how well you upkeep the tank and aro.

Mine is 30"

I haven't seen one bigger or fatter in an aquarium.

Not saying its not possible...but I haven't seen one

your leichardti right? If so, nice!

I dont think that lack of trace elements is an issue, it takes many years for an aro of any kind to achieve full size, these fish can live for atleast a decade, so it probably is just that they dont get the chance to achieve their max size. I believe the biggest limit to be the size of the tank. Im not saying the fish grows to the size of the tank because thats a myth, but if a fish has no room for expansion then its growth certainly is stunted. In severe cases the fish grows with deformaties such as spinal misalignment etc. In the wild they do have an infinte body of water but for a 1 meter fish a 20x6x4 tank is basically infinite (its big enough for the fish to not know the difference). The water quality (ammonia, nitrate, nirite) will reduce a fishes lifespan if it is in too high concentrations for extended periods of time. Dont forget though that the tapwater is taken from a river in the first place and I dont think that too many of the good trace elements will be removed coz it costs money to do so so why bother. Dont quote me on that Im just assuming because I dont think people would waste money removing things when they dont have to. Also I think a fish gets most of the trace elements it needs from its food as apposed to the water.

I think that a fish will get to its maximum size if it is kept in the proper environment for long enough to do it. I dont know anyone who has kept a fish until it died of old age, if anybody has, post its age, length, any deformities it may have had. We would all be interested to know. Wait, I did keep a fish until it got to its max size. It was a Pangasius sutchi, and it ended up exceeding the size that it was supposed to achieve (size taken from various books aswell as internet sources). I think that is good evidence that a fish can achieve its max size if given a chance.

Nicely put. I still think their home waters are better for their growth. Even though you say it comes from a river, we all know well enough its not meant to be drank, that's probably where stuff are added into our water to make it safer. Those little variables which include trace elements and minerals, and a constant fresh supply of water from their waters can mean better growth for them instead of our tankraised pets.

Even if our tankraised fish can grow equally or surpass their wild counterparts, I'm sure those wild counterparts are growing bigger and faster nonetheless, so by the time our fish grow to their size, they're most likely bigger. I dont know, just my thought. What do you think?

 

[piscevore]

100% agree, There wont be the ammonia, nitrite etc which i think has an effect in the wild. Also dont know what chemicals are added to are drinking water that will effect it.
