recommendation needed on setting up an 188 gallon tank

[coolbucks]

Hi Bro Rosha and Vinz,

wow, thanks for the advices from you all.. Agreeded that a big tank will favour arowana spieces...

Bro Rosha, what do you mean wire shock and plant will hairwire like him???

LOL, yes, please explain I was scratching my head too when I read that...
Anyway, I'd imagine since arowanas live in rivers that have plants, an aro in a planted tank should be fine. right? or does my logic have holes in it?

hello bro

aro sometime suddenly get crazy lah.....that what i meaning

Saw a documentary b4 that aro actually curl and spring out of water in the wild to catch insects for food.

The only limitation of planted for aro, imo is the space avail. If its a heavy planted tank, unless its a 6ft, my guess is that an adult aro will feel cramp up.

Cheers

ic... but funny thing is that if in an planted tank, the arowana should feel calm that they are in an natural surroundings... As mentioned by bro xnsdvd, arowana came from river...

Like bro Solonavi, space is the most important factors but I do understand home rear arowana seldom grow to the max of more than 2ft length. As they are rear from the begining in an tank...so call home breed spieces... Like arowana hobbist created width space tank for it to let arowana feel in an wild surounding... Dun know am i thinking in this way is wrong???

bro Solonavi, still remember which site provide you the documentary??

The arowanas you're refering to are the amazonian species. I think they're called "Silver arowanas" in shops. The ones with the more slender tails. These guys can actually jump over a meter out of the water. Bloody cool Not to be confused with the austrailian baramundi(Pearl arowana)

As for your aro never reaching full size... Here's the explaination:
Nitrates. Why? take a hint from discus breeders. These guys do several water changes a day to ensure maximum growth(and lots of feeding and blah blah) Why? because high nitrate levels stunt fish growth. Well, bone growth anyway. Logically, the smaller your tank, the faster the nitrates build up. Which is what gave rise to the impression that fish will "grow to fit" a tank. Aros in the wild have VERY low nitrate levels to deal with, and even less metals/cholrene. Rain water is essentially distilled water in case you haven't noticed. Hence their larger size compared to tank grown fish. And they also have a more varried diet. so nutrition also plays a part. Simply put, keep your nitrates low, if you can, do water changes with distilled water. That and you can't "shock" your aro with pure water so it's safer.
