What Do Jellyfish Eat?

It’s a common question – What do Jellyfish eat?

Most jellyfish love to be fed on live baby brine shrimp or frozen baby brine shrimp. In the wild, brine shrimp will commonly be a jellyfish’s diet.

We sell Baby Brine Shrimp Kits, to allow you to easily hatch your own fresh baby brine shrimp, ready to feed to your jellies.

Jellyfish also accept some types of dried planktonic or substitute dried planktonic foods such as Ocean Nutrition Instant Brine Shrimp, which is available to buy from our online shop.

We’d always recommend to feed live baby brine shrimp alongside dried food, to provide further nutrients, and to keep your jellyfish in peak condition. This is necessary for Amakusa, Purple Stripe Jellyfish (and other types of “sea nettle” jellyfish) especially.

The red bits floating in the tank are the jellyfish’s food – in the centre of each Moon Jellyfish are four “stomachs” which are slowly filling up with food. See how their stomachs are lighting up red!

How Often to Feed Your Jellyfish

Generally speaking jellyfish should be fed daily, but jellies don’t need food in the same way as we do – instead they use food for growth!

So, if your jellyfish is getting too big, put him on a diet – feed once every couple of days, and you’ll see him shrink in size.

Vice versa, if you want your jellyfish to increase in size, try feeding twice daily.

We supply various types of jellyfish food, from live food to dried food, depending on your feeding preference.
