I got a new multi set up for Christmas, but it was only a 10 gallon tank so I'm planning on moving them to a 20 gallon long. I have 6 multis and I believe there are one adult male, two juvenile males, and three females. I want to add a few dither fish and try some ghost shrimp but I'm wondering if I should have those already stocked in the 20g tank when I add my multis into it, or should I have my multis get situated before I add the dither fish or shrimp? I'm thinking my shrimp might live longer if they have a chance to claim some hiding areas before the fish do, but I'm not sure. I realized the fish might eat the shrimp. Any insight?
