As the poll states, how important is it to introduce fish in the “proper” order (I.e. least aggressive to most aggressive). You see it written all over to introduce species in the right order, but once a tank is up and running for a few years you certainly need to address fish losses and can no longer worry about stocking order. In today’s world of COVID-19 fish shortages should we worry about order of introduction or just take what we can get when we can get it?
