assuming you add another 44 inch.. which equals 88 inch, 84 inch for simple calculation.... you are looking at 7ft x 2ft x 2fti can add another 44 inch to the length if i remove a tank, and i also can add 6 inch to hight (tank i have is 44 inch long, 24 inch front to back, 18 inch high )
predator means what i want is -
mostly active , piscivore , love to hunt their food , if not possible at least carnivore, love live food, don't grow too big.
my most fav is goliath tiger and or payara/vampire tetra, but my tank is not suitable for them
availability of indo tiger is very low, you can say rare, all types of gar ia available here, but as you know gars are stiff if i keep gar i need to add more space front to back, that i can't do, arwana is a good idea, here bichirs and snake head are available but still my tank is too small for all of them for long term keeping, and i don't like eelsassuming you add another 44 inch.. which equals 88 inch, 84 inch for simple calculation.... you are looking at 7ft x 2ft x 2ft
then i think you are opening up yourself to a lot more options, indo tigers, florida gars, asian arowana (subjective), kelberi peacock bass , bichirs, eels, etc
