I decided to buy a Triop kit and grow some Triops. My kit came with one of the round plain tanks that is around a litre big. I have been sucessful as I have nine triops all around a centimetre long and all 9 days old. I read on a website that you need 2 litres of water PER adult triop, and i have nine, does this mean I need to transfer them into 18 litres of water?!?!
