So I landed up not getting the SDs but I got 17 x Desmopuntius johorensis instead.
I hadn't come across these fish before but doing some research instore they seem perfect for my set up. Not to mention they always swim in a tight school around my wood and roots. I am very pleased with these little guys. And they eat in a frenzy type manner when they smell food .
