I just went to a lfs
yesterday and the guy recently set up a 120 and put a pile of rubble in the the back of the tank then built his rock work over and around it for a pod population. Looks like it will work pretty good. Maybe try that. I have a 20 long fuge on my 55 and I really don't have a good population in the DT or the fuge. I find few in my filter sock weekly and see some monsters in my fuge but not enough to sustain a fish that would rely on them. I have a couple peppermints in my fuge, I'm not sure if they snack on them. Maybe ill put a small hob
with rubble in my sump and see if I can get some population.
Stock: 6 line wrasse, hawk fish, yellow striped maroon, fire shrimp and a royal gramma.
