If you haven't seen these frozen foods called cyclop-eeze you need to check them out. these are by far the favorite thing for my fish to eat, they are like little red amphipods and copepods. If a fish turns down these there is a good chance they just plain won't eat frozen or dry foods at all. even the larger polyp sps will eat them, my tenuis catches them pretty easily. I never knew how many people didn't know about these things until recently, so I decided to do this post.
