to me as long as the fish can maneuver and move freely in any given position the tank is adequate for it regardless the size of the fish or the tank..of course the bigger the better,,isnt it all our dream to have an tank as big your house for your fish?
lets say the the arowana is 5 inch and the tank only 10G..i dont see a problem with that as long as all parameter and everything taken care of, i will question people who has 5 of 5 inches arowana in 10G tank though.
did a little math of 5 inch fish in standard 10G (20Lx10Wx10H). thats 8.7G volume of water.
to make it simple math for the sake of argument for some of you lets say the grown up arowana is 25 inch which is 5 times of that 5 inches arowana..that means that 10G has turned into 100Wx50Hx50 thats turned into 1,082G of volume of water. *these number measure in inches and gallon of US measurement*
im sure there will be less than 0.1% of MFK arowana keepers has that many gallons in 1 tank
so when someone flaming or "advicing" a person for keeping his 5 inch aro in 10G and not questioning some one who is putting his 1 grown up aro in 500G tank is beyond my head LOL. thats just contradict the "advice given"
some people comments here that its waste of money to spend and buy bigger tank to accommodate the growing up fish, let me tell you something who are you to tell them that? did they use your money, are they your kids?
we are in the forum, we communicate with writing and thats it, we exchange communication thru it and thats it, if they asked advice feel free to give if you know one and proven to be working for you. if they dont ask why give advice?
problem is alot of them never ask advice in the first place alot of them ask for a question or 2, and most of so called 'expert" giving them advice when the "noob" asked for a question instead of answering if (given they know the answer), me the third person(neutral view) looking at the thread that created clearly can see the retard.
