I suppose so but I couldnt confidently say since ive not kept an adult aro.Even if it only reached three feet, still a tad tight don't you think?
It was said somewhere in the beginning of the thread regarding why silvers dont reach 4ft in captivity.Who here is saying that? I suspect plenty of other species of aros are also abused in captivity, but the difference, and it's a BIG one, is silvers are dirt cheap in comparison to an Asian aro. Fish that are dirt cheap are easily replaced, kind of like an Oscar that gets funged up from spending years in a 55 gallon.
The comparison im making is we have some saying they dont reach their size potential and die prematurely because they need to be kept in larger tanks and this is the sole reason for the lack of size. polyaddict asked if anyone seen a 4ft aro in person. Not kept in a pond. Better off you read the beginning posts of the thread.
