will you please tell me length instead of the fish I dont want an arowana until my parents get their huge tank thats 400+ gallons 125 isnt big enough for arowana anyways it needs a wider tank and also I want to have some smaller fish that an arowana would kill

Answer 1

The general "rule" should be that the fish should be no longer than the shortest measurement of you tank for turning, so you shouldn't have anything longer than 18".

That should accommodate any of the larger plecos, a giraffe nosed catfish (Auchenoglanis occidentalis), a few clown loaches, a black ghost knife, some of the freshwater "eels" (fire, tiretrack), iridescent shark, an oscar, Jack Dempsey, Buttikoferi cichlid, or channel catfish. You can also get a school of slightly smaller schooling fish that need that sized tank for swimming space, like tinfoil barbs or bala sharks

Answer 2

Arowannas do get huge and your tank isn't big enough for an adult. It'll fit, but it won't be happy.

The "1 inch of fish per gallon of water" rule is so general and really not good. A fat and wide fish that is 3 inches long is going to have a bigger bioload than a slender fish that's 7 inches long.

You're much better off to just research some fish you might like to keep, then ask if they would be a good match for your aquarium and if they are, how many you should get.

liveaquaria.com has tons of information on fishes, and drsfostersmith.com has tons of articles for you to read. =)

Answer 3

A school of 5 Bala Sharks would love to be in that tank. They get about a foot long each and are fast active schooling giants.
