I just made a new batch that my fish seem to enjoy the best so far. This is kind of close to SM's and others blend but with gelatin to keep it held to gather a bit.
I used a can each of peas, carrots, and about 3/4 pound of shrimp. I heated the veggies in the microwave for a few minutes while I peeled the shrimp. When done heating and peeling I added this to my blender and blended until smooth then I added the 2 small envelopes of gelatin (comes 4 to a box) and blended for a couple more minutes. Then I poured into three flat/shallow containers with lids and then put in the fridge over night to let the gelatin set-up. The other two containers I put into the freezer after they set-up to use later. This seems to be a big hit with my SW fish and the Reef animals seem to enjoy it as well seeing that it breaks down into smaller pieces that they can handle.
Just an update on this last mix of food. I was watching my dotty back (Pseudochromis porphyreus) eat this mix and was observing my mandarin (Synchiropus splendidus) also eating this. This is the only mandarin I have ever had that has not eaten anything but copods and the like. I was truly amazed by this act.
For a Fish Only or FW tank this mix could use a little less liquid or a little more gelatin as it separates very easily which is great for my SW/reef tanks but not the best in the FW cichlid tanks.
