Sorry, but I haven't found any in english.
but most of them involved beefheart as well
Some hobbiests use meat from warmblood animals. But because they contain fat, heart too although less than meat, don't put those into food. You can also use frozen saithe. If you give meat to your fishes, they get ill easily - fat remains e.g. fishes' liver and liver doesn't work ok after that. Fat causes different internal illness.
Here you can find one recipe (in finnish)

It will be good, if you check first do your fishes eat e.g. banana, because first time when I did Räkmix, fishes didn't eat it

They did not like banana
