I have a 125 reef so he won't run out of pods. Plus my sump is full of pods. Every once in a while I take a big handful of chaeto out of the sump and shake it out in the main tank.
Plus, behind all of my rock, I have about 6 "pod piles" of reef rubble for them to hide and reproduce in. No danger of running out of pods. I'm just glad I'm not irritating him when he does that. My husband wants to see the blenny display, but he only does it for me, lol. He says my fish is in love with me. Jealous of a fish.....too funny.
