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
 
If you want an arapaima or a tiger fish or barramundi you better be getting a huuuuuuge tank. I would say that the armatus is the slowest growing and would be ok in that size tank for a long time, possibly same with the wolf fish.

Armatus grow quickly and I realize a bigger tank would be necessary but that wasnt the question I was looking for an actual estimate of time, months,years ect..
 
tbh what your asking sounds irresponsible just get a tank big enough to cover the fish its whole life to start. its not cool to have a "toothy predator" in a tank its gonna outgrow soon.
 
save youself some money and heartbreak. The pike requires water that is too cold for most of those species listed. Not only that they are some of the most badass native predators and will quite literally attack anything that shows weakness and is not noticeably larger then the pike itself, I've seen reports of pike actually charging boat propellers. especially if it is well established in a territory. One fish or the other would be dead. Either keep the pike or ditch it and heat up the tank a bit.

I don't need your input I have a plan and I don't care what you think is cool or not. Either give a time frame for a 180 on these fish or dont reply.

I've stated that this tank would be for ONE of the mentioned fish including the pike and none of these would be together.............

oh I was confused.

As long as you are looking at pike, try a grass pike it could survive in a 180 for quite a while(years depending on diet) and has a better temperament. If you started with a 3-5 inch juvie I'd give it 2-3 years in a 180 and potentially could do life in a 210 or 265. You also failed to list a starting size to time is extremely variable. The Arapima would not last 6-12 months in that tank if it lasted at all (look for the african arrow if you like the arapima, they grow slower and stay smaller).

Don't know much about many of the other fish sorry. Good luck.
