Hi Wayne,
I can offer an answer: YES, basically, the husbandry is the same for salvator and acanthurus; they require the same approx temp renge (ambient and surface), a similar humidity range, a whole prey diet, both vertebrate and invert, (inverts moreso for hatchlings in both species). Support to acheive their maximum potential....
So where do you feel there are any great differences?
Asking and(hopefully)answering these questions can help us all, MOST importantly, the animals in our care!!
