Sliver Arwona Info Needed!

[TigerMan]

thinking about getting asliver arwona need info on them and would a full grown one be able to live in a normal 30gallon?

You are joking arent you? Surely you realise that a fish which reaches 4 feet in the wild and at least 30 inches in captivity cannot go into a 36" long tank?

 

[TigerMan]

ok so what's the min tank size for them?

 

[CFC]

A 10x4x3 (about 900g) would be a minimum for a full grown adult, you could start one off in a 4x2x2 (120g) and then upgrade every 6 months to keep up with the fishes growth.

 

[TigerMan]

are you serious that's huge !!!!!!!! is there any other tank that would be smaller it could live in ( are we talking about Us gallon's??)

 

[CFC]

Why would you want to keep them in a smaller tank? They are big fish and need big tanks, if you cant supply this then you should not buy the fish, its as simple as that.

Agreed. I'm not a great fan of giant fish, and really there are lots of just as interesting smaller fish that would work fine in a 30 gallon aquarium. If you want something that is sleek and/or predatory, consider:

* Dwarf snakeheads (e.g. Channa asiatica, Channa gachua)
* Dwarf pike cichlids (e.g. Crenicichla notophthalmus)
* African butterflyfish (actually very closely related to arowanas, keep in groups)
* Celebes halfbeaks (can be mean tempered, but fun to breed)
* Pimelodella pictus catfish (eat everything they can catch, but very pretty)

... to name but a few.

You can easily find these fish, and they can adapt to relatively small tanks as well as survive on frozen or flake foods. I kept a Channa asiatica for a while, and it was a delight. OK, it looked mean, but in fact it was very peaceful and easy to look after. Happily ate squid meat and prawns.

900 gallons? Okay, personally, I think that is a bit xtreme. 125, that is the minimum I heard.

a silver arowana can easily reach and exceed 30" in length. a 36"x36"x24" tank would be barely large enough for such an arowana to swim in circles; that tank is still 135 US gallons.

Thats why you keep bettas and not tankbuster predators

A 125 gallon aquarium wouldnt even be large enough for one of the smaller arowana species such as the Asian and Australian arowana's which rarely reach more than 20 inches in captivity, even these require tanks in the region of 300 gallons eventually though it is widely accepted that a 180 gallon aquarium is just about acceptable as long at it wont be the fishes permament home.

The minimum space needed for any fish is one that is 4 times its length long by 1.5 times its length wide, the tank also needs to be at least the length of the fish tall, this provides the bare minimum area for a fish to swim and turn in without bumping into the glass continually. Taking these dimensions from a fish that is 30 inches long gives you a tank of 120x45x30", around 700 gallons. However glass sheets come in pre cut sizes to the nearest complete foot and to have the glass cut down to the odd numbers would cost extra so you would actually most likely end up with a tank of 120x48x36" which is around 897 gallons.
Even if you provided the fish with half the space it should really have you still end up with a tank of around 450 gallons, far beyond the means of the casual hobbiest and a huge undertaking in time and money.

How much is a 900 gallon tank?

 

[Paul_MTS]

probable around £3k for the bare tank alone.

I have been curious myself, I've been amused by Arrowannas pretty much since people on here have been talking about them (Or as long as I've been here, but there seems to be a craze going on now...)
I want to eventually keep rays and arrowannas, and other larger fishes....I was wondering whats the smallest arrownna, or an arrowana that can comfertabley live in a 220 US G tank?

A jardini arowana could easily be kept in a tank that size for life, the trouble is finding tankmates that they will tollerate as they are also the most aggressive and the most powerfully built species of the 6 known species. Asian arowana's would also work but are illegal in the US.
