I've heard that feeding Freshwater shrimps (live or frozen) can or will enhance the redness of an arowana. I've been feeding the shrimps live to my aro (with the horn cut off) unshelled eversince i bought him. The shell has caratenoids or something that induces color pigmentation. So far, i don't notice the effects but the redness is coming out naturally since the aro is getting older. Does anyone feed their red aros shrimps, any suggestions or comments?
but i just drop the live shrimps into the tank and if my red gets hungry he'll just scoop up a few.
