Black Aro vs. Silver Aro?

[daveman12345]

Hi guys,

I'm trying to find more information about Black Aro's. I googled around but haven't found any really good threads or articles. I successfully raised a 2 foot Silver and am starting to raise a baby Jardini. I would like to include a baby Black Aro with the Jardini so that they can grow up together.

Now, my main two questions are:

- Are there any different traits with the Black Aro? Are they any more aggressive?
- Is there any difference in raising them, or are they the same?

blacks are better then silver cause they dont get drop eyes i hate silver cause of drop eye problem so i stick to black aro

Raising something with a jardini won't make it tolerate it as it gets older. It's a case by case basis, but the majority of jardinis will kill all tankmates when they hit the 8" mark, for some 10". It would suck for you to wake up one day to a dead black aro.

Black aros require basically the same care as silvers, even the same sized tanks, since both reach around 4'.

When they get much older, most silver aros turn almost white, and they become beefy. Black aros retain their dark pigmentation and remain mostly slender (in comparison to silvers). Most retain black coloration at the very tip of their fins for the duration of their lives.

Some blacks can still get DE. It is rare, but it happens.

Thanks for the info. I'll see what I can do. If they don't tolerate each other, I'll have to figure out a tank situation by then. It looks like I'll shop around. Since you're from LA Roberto, do you know the price around SoCal? I think I saw a 5" for $110, but that was a year ago. I hope they've dropped..

I think they're about the same. Saw a 7" for $150, so yeah. That's the good thing about silvers, you can probably get them for $30 at that size.

Wow 5 times the difference. There must be a reason that they're so expensive. Are their breeding habits much more different than Silvers? That should be one of the main differences then.

the reason for the big price difference is the silvers are captive bred(over-bred with a blurring gene pool), while the blacks are all wild caught and being imported less regularly than in the past- some say the blurring gene pool the silvers are coming from is also the reason they all get drop eye and the blacks dont-
juxtaroberto was mentioning how rare drop eye is in blacks, and it must be, because Ive never seen a black with it, and Ive had blacks consistently for many years
to try and have a jar and a black live together for an extended amount of time is almost impossible, some members will show a picture or two of a black and a jar together in a tank, and pat themselves on the back and say how everybody else is wrong, and that it is in fact possible, but then it comes out that it lasted only an hour(usually the case), a day, a week, a month, or maybe a year, but to me at the end of a year if you end up with a dead black, its not a success-
the size difference needs to be so great, that in the beginning you run the risk of the black eating the jar, anything less and the jar begins pestering the black- certainly when then the jar hits a foot, its probably already killed the black

Great post. I've seen Jar's and Silvers together. From your post, are you saying that Jar's and Silvers can't get along together, or specifically that Jars and Black Aro's can't get along together?

Platinum is far more expensive than tinfoil and they're both similar...

Raising blacks is the same as raising silvers, special care should be taken with any arowana under 10" IMO. To many there is no real difference in the looks between the two, though this is due to lack of experience and an untrained eye. For the few who have done the research or kept both the difference is very apparent. The aggressiveness depends on the individual, blacks are generally less skittish but more cautious. My two blacks have grown to be very outgoing tough.

Baby silvers can be bought most anytime of the year, whereas baby blacks are only available in the spring/early summer. They are or have been banned from export out of brazil. These are a couple of reasons for the higher cost.
