We have a single Percula Clown Fish that seems to like frozen brine shrimp a lot. The problem is that the portions that the brine shrimp come in are way too big and unmanageable. The shrimp come in frozen, 1 cm cubes that need to be cut apart either with scissors or a knife, or smashed with your fingers when they melt a little. Not feeding the fish a consistent amount ended up causing an overfeeding problem.
Step 1: Supplies
You'll need some supplies in addition to the frozen fish food.
Waffle pattern mold:
I used a silicone pot holder with a grid pattern that I got from Bed Bath and Beyond. They don't seem to carry it online but here's the same one from Amazon.
Get a cheap flavor injector anywhere you can. A simple syringe will work but make sure it has a large diameter so the shrimp don't clog up the needle. Bed Bath and beyond
Cutters or sharp scissors:
You'll need these to cut the beveled tip off of the flavor injector needle.
To hold the melted shrimp mixture.
I'm using a shot glass.
Frozen brine shrimp:
Purchased from Petco.
One or more fish to feed:
Step 2: Prep
Prep all your equipment. I started by cutting the beveled tip off of the flavor injector needle so I can get all of the shrimp out of the container.
I also washed everything to make sure there isn't any contaminants from the manufacturing process of any of the new items.
Step 3: Prep Continued
Prep the shrimp. Place a small amount of warm water in your container and then add one cube of the frozen shrimp. I make small batches because it seems to last a long time but feel free to make larger batch if you have the need. Swirl the container around to melt the cube. If you put too much water in, don't worry. After the cube has melted, set the container aside.
Now we're going to remove the extra water that we used to melt the shrimp so we more concentrated cubes. You could also skip this step by just letting the frozen cube melt down on its own. Get your flavor injector and reassemble it if you haven't already done so and your silicone pot holder. Put the pot holder on a flat surface, preferably near the sink.
Now grab your flavor injector and push the plunger to the bottom. Pick up the container with the melted shrimp in the other hand. Tilt the container slightly and with the needle, suck off the clear layer of water, using your thumb to pull the plunger up. If you pull up some of the shrimp, just gently squirt them back in and try again. Squirt the water you've removed into the sink. Once you've removed the extra water we're ready to make some shrimp ice cubes!
Step 4: Suck It!
Using the flavor injector, push out all the air with the plunger and then suck up all the shrimp from your container. Now using the silicone pot holder as your ice cube tray, fill the squares with your needle. If you put too much in, put the needle back in and suck the extra out. Repeat till the syringe is empty.
Step 5: Freeze 'em
Carefully place your pot holder into your freezer. Let them sit for a half hour or more to set up.
After they've frozen up, it's time to de-mold them. Grab your storage container and flip the pot holder over and pop your mini shrimp cubes into the container.
