I've seen folks mix Zebrasoma's. I would love to have a desjardinii too. My lfs, that sells the serrulata, feeds it to a Z. desjardinii. Had me hooked on the idea when I saw it. I hope it's good for nutrient export. The lfs cuts it back often it seems. Feeding the tangs will be fun, but I need it to w o r k. Thanks skinz!
