The pearlscale is the commonest of the ‘novelty’ fantail derivatives in Britain, although it seems to be less often seen now than ten years ago.
It breeds true to form but it is a challenge to introduce the full suite of calico colours in addition to the orangey-white usually found. The pearlscale is a very lively fish.
The colour may be metallic (self-coloured or variegated in a pleasing pattern and similar on each side) or calico. Metallic colours should appear as burnished metal, extending into the fins. Calico fish should have a blue background with patches of violet, red, orange, yellow and brown, spotted with black.
