I don't use frozen food, it's never worked for me. Freezer burns most the time and doesn't really hang in the water column where I need it to. Most of it just seems to last about a month and then "freezer burn". But chicken legs do the same thing haha
I hate to sound like I'm pitching something but I've been fragging corals for 15 years. Friend or mine got me turned on to Olio Coral Food. I don't even refrigerate it (I think you're supposed to, but meh). Stuff is crazy good though for a full spectrum food. Most the fraggers I know use it, but not many are on the boards. I even use it for my clownfish breeding tank cause I don't know if whoever makes it intended it for it, but it even feeds my fry when my Piccasos breed.
Which by, wait can say this on the board here, another spawning just happened if anyone likes Piccasos.
