I am lucky to have a section of the freezer to myself when collection daphnia I often freeze a lot of it a culture and lots of fruit flies so freeze some of themAh, that's good to know, thanks! I've always just stuck them in my fish stand cupboard and within 24 hours they're climbing the sides.
Speaking of live foods though, @Colin_T remember I was making mosquito ice cubes recently? I just went to change my dog's water bowl and found it full of mosquito larvae. Turns out my mom wanted to cool her water for her and chucked an ice cube in there, not realising it was my fish food! Hmmff. Oh well. The dog would have loved it anyway.
