This guy is so awesome. He has several great DIY things for his aquarium and he totally just shares it with everybody. I'm going to build this feeder this weekend. I have a mandarin dragonet and it's always so skinny! I purchase copepods for it, but who knows how many actualy come in those bags and how many actually make it to the mandarin.
This is such an easy and cheap project and it works! I'm also going to build a brine shrimp hatchery to obviously hatch baby brine shrimp to use in my feeder. Also and easy and cheap project. I'll post pictures when i get started, but here are the links for both from Paul B.
