wow thanks... yeah its def a silver than, 25$
what do you think my next tank size should be?
I would jump straight to a tank that can house a fully grown silver for life after it grows out your 100. It will save you money, as the silver will outgrow your next grow out tank fairly quickly, and it will save you the trouble of wrestling a 2+ foot fish which might cause the fish some damage, and possibly damage to your floors and walls from being soaked from the splashing. You probably have a year at the most to upgrade so plan fast.
Since all arowanas grow pretty large compared to the average fish, aro owners normally recommend tanks by footprint dimension (length and width) to better suit their needs instead of tank volume. Many experienced aro owners from MFK recommend a tank with a 8ft x 2.5ft footprint to house a silver for life. The silver needs at least 2 times it length to swim and at least 2 feet to be able to turn comfortably without having to back up, though a 2.5 foot width is ideal since they can get quite thick when fully grown. So the absolute minimum tank would be a 240 gallon tank with the dimensions 8ft x 2ft x 2 ft, but ideally with a 8ft x 2.5ft footprint you are looking at 300+ gallons. If the width is not big enough for the fish to turn, and it has to keep backing up to turn around, this might end up causing gill curl where its gills curl outwards exposing the soft tissue inside. If the tank is not big enough, it might be stunted and spinal deformities like humps can form.
Also Silvers are very very skittish, especially when young. Make sure to weigh down your lid and properly cover your tank because they are known for escaping the tank and killing themselves while no one is home. All it needs is a slit as big as it is wide next to an opening for the filter tubes for it to escape. As it gets bigger, it gets much stronger. Do not underestimate their strength. Giving them a nice big tank helps them to be calmer. In small tanks they will feel more trapped and are more inclined to jump. There are instances where aros have jumped, failed to escape, but broke their backs instead. There are also instances where aros jump, successfully escape, but fall so hard that they cause brain damage or break their own backs on the floor so even if the owners are home, they are severly damaged. Normally though they are notorious for committing suicide while no one is around to save them. So providing a big home will increase its chances for survival.
If you cannot provide this fish with a large enough tank soon, you should seriously reconsider re-homing it. The larger it gets, the harder it is to sell or give away so do not plan on trying to make money from selling it when it is large as most people know they cannot properly house it either by that time. Plus it will cause you much stress and trouble. I've met and heard of plenty of people whos aro has gotten too large and they cannot afford a big enough tank and no one will take it. So eventually after calling everyone in town, they have to donate it to somewhere, like a lfs or aquarium/zoo, if they're lucky. Sometimes the Aro jumps out and dies while the owner is searching for a new home and sometimes they are even forced to euthanize it. Don't do this to yourself and don't do it to the fish.
So do some research and plan accordingly. This is a good place to start your research, it will save you a lot of time in finding info.
