If you are making a custom tank, I would highly recommend a deeper tank. My arowana essentially outgrew the 100gal (18 inch deep) when he was about 14-16 inches. I think a general rule of thumb would be the depth should be 1.5 the length of the fish. So a 30-36 inch deep tank would be best for your 24". If weight is an issue, I would highly recommend a corner tank. Mine did much better in the 90gallon corner tank than the 100gal 6ft tank. If you are making a custom tank, it should be easy to do a corner, or other type of deep tank.
Ty for ur suggestion mate
Well as far as i know, Asian arowanas r mostly middle to surface level swimming fish so depth is not an issue for them unless ur keeping loads of tankmates like Gars,rtc,tigers, etc...who r bottom to middle level dwellers.
2 feet is enough height for them and the depth shouldn't be 1.5x the length of the aro , the width should be at least 1.5-2x the length of the aro so it can turn around easily...Im considering of making the width a little more to 2.5feet so he can turn around easily.so say 6x2.5x2. Tis tank is a temporary tank thats why he is mostly staying at the bottom but in his previous growing tank(which is currently housing a juv xb) was 4x2x2 tank and he never actually went down below the 1.5ft level depth,i.e, he was always swimming above the 1.5 ft level mark on the 2 feet depth tank
What do u mean that ur 6ft tank was 100g? Maybe it was a 6x1.5x1.5 dimension tank? If thats the case then yes the width is too small for ur aro which is already 14-15 inches in length
For aros, length and width matter the most, depth should at least be around 2 ft but thats more than enough for an asian aro to live a lifetime \m/
Will update when the tank is ready and the resident has been shifted there.
arowana's have no 'freedom' in USA, yet? I hope yet comes in...
