dorado still must be a bank breaker to import as juveniles though, i suggested armatus because of your tropical fish list they're probably the easiest to import as juveniles and won't require 5 digit tank gallon sizes.
i've never even heard of captive dorado so I cannot elaborate on them. it's illegal to own many game fish in north america without a permit, pike included. i said bowfin are easier to get because they are catagorized as coarse fish, you don't need the permit, plus they count as fish caught so if you eat pike you will only be allowed to take one home instead of 2.. tiger muskie are a hybrid of pike and muskie, I don't think you need a permit to own them but very few fish farms raise them and those that do tend to sell in bulk only My bad for armatus, I was thinking about scombs, which gets about pretty big and are very energetic. you'd still need a tank in the high triple digits to keep them. As i said they can be very aggressive with each other and often kill others of their own kind, especially in aquaria

There's a huge difference between what a fish will grow to in CAPTIVITY vs. what it will grow to in the WILD. Notice both of those pictures are of fishermen who caught the specimens in the wild. Armatus in captivity max out around 24"
i'd rather plan for wild size then captivity size to be safe.
It's just my philosophy.

well i'm not keeping any monsters at the moment or for at least several years so it's not a issue for me. I'm just saving up for my next aquarium, a 75-100 gallonI love your philosophy, but my check book doesn't![]()

I have a 180 gallon and I'm looking for a toothy predator to inhabit it for awhile until I get a bigger set up. This leads me to ask how long I would be able to keep the following fish in there for by themselves or with another of the same species.
Goliath African Tigerfish-
Armatus-
Hoplias Aimara-
Vitattus African Tigerfish-
Barramundi-
Arapaima Gigas-
Golden Dorado-
Just list the amount of time until they would grow out the 180
