Hi guys, just wanna share my recent study of arowana's scale problems.
History: I've been keeping arowanas for years, golden ones, and have been experiencing many of the common problems that most amateurs face. Gill curl, drooping eye, chipped scales, etc. Took me quite some time and lots of solid research done to finally find a solution for diminishing scale problems.
Process of Receding Scales
It all starts from a little edge abrasion. Whenever the arowana makes a turn, its body will bend, causing the scales to rub against each other. Weak scales will experience abrasions from the edges of neighbouring scales. This causes a "chipped" effect. However, it doesn't happen overnight, it is due to constant abrasion from movements.
