. . . . 24" width wont be big enough for asians... i know many people and have seen
many that are 24-27" + so the bare minimum width would need to be 30-36" looking
at a ideal 84" (7') x 30"/36" (30"-3') x 24" (2') as for color it's what you can afford and
what you like.
the cheapest asian arowana are green & banjar followed by the rtg (red tail gold),
then hbrtg (high back rtg). then you have the goldxb (gold cross back) and reds
like the chilli red. then you go on to the premium like blue base goldxb, super red,
24k goldxb 24k goldxb gold helmet/full gold helmet, albinos, platinum & other man
made morphs with different base colors and etc. you also have to factor in the
quality of each specimen.
