It would actually be something I feed on a regular basis, normally once every second day. But I won't be feeding my big guys for three days since they had a bunch of live platies yesterday, and they're all very fat. Usually every month I go to an Asian market and buy a bunch of frozen and fresh food for my fish, which include a few different small to medium sized fish, a couple types shrimp, mussels, clams, oysters, krill, and salmon eggs (for the ropefish primarily), every other month I get crab and lobster. Normally Asian markets are the only place I can buy these foods, what I can find in aquarium stores are very expensive, now the only foods I buy there are brine shrimp, bloodworms, mysis shrimp, and plankton. I used to spent around $150 on frozen and fresh foods a month (not including live), some times $200, now I'm only spending about $70-80. Once I get everything I make up 15 bags for each tank (60 in total) and freeze them, that way I can just thaw the contents of them out and feed them, rather than getting all the food out each day, cutting it up and such, it's just less of a hassle. I've already cut up, bagged and froze all of it, for my big guys I did add it into their bags, but I only cut them in half or left them whole, so I could just pick them out, but I only put 2-3 in each bag since I have no idea if they'd even like them. For the African cichlid tank and my grow out tank, I cut them up very fine so they could eat it, I just didn't put mix it with their food, instead I just layered it in a bag so I could break off a piece when I thaw out their other food, if they did get them, it would probably be equal to one for the cichlids, and half of one for the grow out tank, and that would be spread among all of them. And I didn't give any to my axolotls, since they're picky anyway, they might like them, but if they don't, I don't really want to pick them out of the tank.
Also, regarding the roast beef part, that sounds very unhealthy. That was always one thing I wanted to be very careful about, I don't like the idea of feeding anything to my fish that they don't have access to in the wild. Even beef heart, I know it's okay to feed with a bit of moderation, but it seems almost wrong because it is a land animal. That's why I was curious about cooked snails, but as long as it won't hurt them, I'll use it. And I definitely won't be buying it again, unless they're raw. I'm usually much more careful with that sort of thing, I guess I was just so excited that I saw them that I didn't even think to look.
