Wah, so nice your arowana! I also in the middle of preparation to setup a tank and yellow tail arowana / banjar red arowana will be the best candidate.
BTW, it is true that banjar red arowana will be change to yellow tail (the tail) was it matured? What I mean is, the red tail of Banjar Red will turn to Yellow once it matured? it is true? or can anyone shows the picture of matured Banjar Red Arowana..please...
