demon: rtg isnt much more, litereally, there is a huge jump with a RTG and a super read.
Banjar and RTG is closer in price, B UT
its your first aro, why not get a cheaper one, in a few years, sell it and get another perhaps? its a learning curve i reckon.
tanning is the use of bright lights in the path where the arowana swims past the most, some even put it on the side of thetank, i didnt, it spooks it.
this bring sout hte colours.
also the background matters.
put a black background, back and sides for the 1.5 or super reds and red aros i was told, i also used black or dark gravel.
this colours them up too.
i used to begin with 2x 4 foot lights, aqua glow and a power glo.
n the stickys, there is a tanning info one. check it out.
there is no point of going hardcore with metal halides and stuff, cos banjars will only colour up to a certain extent - if youb uy super reds, maybe worth investing in metal halidse and the like
a few bucks more and i could get a super red and so on and so forth
