I'm surprised to see that this thread doesn't already exist (unless I missed it). I'm pretty new to the hobby so maybe there's already a consensus that I haven't heard, but anyways here's my deal: I've got a small saltwater predator grow out tank with just a small 3" porcupine puffer and a ~12" snowflake eel. The puffer's been eating krill and chopped up silversides, but I'm going to try to get him onto clams and squid as well. The eel almost exclusively eats silversides, but now that the waters around me on Long Island are warming up I thought I'd drag my seine net through some grasses and see what I could pull out for him. I thought it would be nice to freeze a few bags of grass shrimp to have on hand. The silversides I feed are also local caught. I'm a regular fisherman so I have a freezer full of local caught bait. It just seemed foolish to spend $15 for a bag of hikari when I have too much on hand already. I also fed him the fins from the squid that I caught back in November. I was a little nervous about feeding unsterilized food at the start, but I've had no problems at all for 6 months now. My question is, is this a safe long term plan? I'd really like to know before I get into this freezing cold water. Thanks!
