My aquarium is exactly 5 months & 1 week old. I started with a combo of live rock, dry rock, live sand, and dry sand. I'm thinking about adding some copepods to the aquarium. I've tried finding them and can't seem to see any? I've used a flash light at night, but I haven't had much luck. It's possible they are there and my eyesight is just bad. Is it possible that my 2 big hermits or Firefish, or 2 clown fish have been eaten the population? It's a 29 gallon FOWLR with 3 small fish, a cleaner shrimp, a peppermint shrimp and a bunch of snails. My LFS carries live copepods (they come in a bottle, but I'm not sure what type copepods they are or what brand/company they come from). I've read that copepods are a good part of the little eco-system and I'm thinking of adding some. What do you think? Bad idea or good idea? Am I just waisting money or actually providing something good to the aquarium? Additionally, I don't have a refugium and I don't really want to culture them myself.
