do you have a sump? how long has your tank been running? you have a good bit of LR in your tank, which is good, but i'm always leary about adding more than one pod-eating fish, especially if you dont run a fuge in your system. you could do it, but if you dont have a fuge where the pods can reproduce then you are dealing with fish that are going to feed off a finite amount of food. you could always buy pods from your LFS, but they are expensive, like $20 for 400 and these fish go through them pretty quickly
