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.

Flavor injector:
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.

Small container:
To hold the melted shrimp mixture.
I'm using a shot glass.

Frozen brine shrimp:
Purchased from Petco.

One or more fish to feed:
They also make smaller cubes, but they are harder to come by. another way to do this is to unthaw the entire cube into a shot glass mixed with some aquarium water (fresh or salt) and use what you need then re-freeze it, it works fine as long as it does not get too warm or stay warm for a long period of time. Also has anyone tried to grow brine shrimp?
<p>Growing brine to adulthood takes some work, but many agree that bbs (baby brine shrimp) are a better source of food. They are VERY small though so you can feed thousands a day. There are a few retail and more than one DIY design for a brine shrimp hatchery. You can buy a little bottle of eggs that has hundreds of thousands (more likely millions). Hatching them is easy, feeding them is also easy. This is not a replacement food though, but it's a good secondary food source, or for specific breeds of fish that won't eat larger or non-living food.</p>
I thought about growing sea monkeys but it seemed like another tank to clean.
Awesome! I can use that same method with daphnia for baby fishies. Doesn't seem like it would work with blood worms though, since they're too big. When I feed my dwarf puffers, I thaw a cube out, feed them the correct amount, then put the rest in the fridge, they hold up for a few days just fine.
That's a very comprehensive and informative guide which I think deserve all the credit it can get. Sometimes I do face the same problem as well and I use different approach like searching for smaller frozen brine shrimp cubes that is only half a centimeter sold in certain pet stores but they cost a lot more than bigger sized cube. Now that you've provided a solution, I'll definitely try it out and I believe it will avoid all the hassles I encountered previously.

i have pufferfish too but i just pop out a cube and cut it with a razor blade to the size that i need, then put the extra back in the square i popped it out of, seal it back up and put it back in the freezer. this is a cool instructable though!!
Don't know why I didn't think of it sooner - thanks! Our dwarf puffers eat frozen blood worms and we've had the same problem with over feeding and messy deconstruction of these cubes to try and get the right amount. Will definitely be trying this out! : )
Very Cool! I have to cut them in half most of the time! Great Instructable!
