Thanks for the advice everyone! I chose the ones with thickest bands, they were not the smallest but not the biggest around 7" but stands out from the batch of around 10 to choose from!!!
Can anyone tell if these are actually WC? These are indeed very shy, they have both swam around a little then both went to hide behind the filter pipes and not moved!
I had these 2 weeksii now for 4 days. The smaller one doesn't hide as much and has eaten everyday till his stomach bulges. The bigger one has only eaten on the first night I got him but has since been laying on top of the filter pipe only moving now and then. Does this position for the weeksii matter?
Not really. He's just thag way because that's the position that is able to keep him in that crevice. If you move that stuff around he'll probably find some other weird position to form to.
