What to Do If Your Peppermint Shrimp Isn’t Eating Aiptasia

Troubleshooting: My Shrimp Isn’t Eating Aiptasia

Thank you for choosing captive-bred Lysmata boggessi from GreenWave Aquatics — the only peppermint shrimp species consistently shown in controlled trials to consume Aiptasia. While these shrimp are highly reliable, individual behaviour can vary depending on tank conditions. If yours hasn’t started feeding yet, try the tips below.

1. Reduce Other Food (24–48 Hours)

Peppermint shrimp are opportunistic. If they have easy access to pellets, frozen food, or flake, they may ignore Aiptasia. Try withholding all food for a day or two to encourage natural foraging.

2. Check the Size of the Aiptasia

Very large anemones can be intimidating for new or smaller shrimp. In many cases, they will begin with smaller polyps and work their way up. You can try trimming oversized Aiptasia manually to make them more appealing.

3. Make Sure They’re Accessible

If Aiptasia are hidden deep in crevices or high-flow zones, your shrimp may not notice them. Use a pipette or turkey baster to gently coax the anemones into extending where the shrimp can find them.

4. Observe After Lights Out

Lysmata boggessi are naturally nocturnal. Try observing the tank at night with a red torch or dim light — you may find they’re already hunting when you’re not watching.

5. Consider Tankmates

Are there aggressive fish in the tank? Shrimp may avoid foraging if they feel threatened. Ensure your shrimp has secure hiding spots and isn’t being harassed or outcompeted.

6. Give Them Time

Some shrimp begin feeding within hours of arrival, while others may take several days to settle and display natural behaviour. This is completely normal — be patient and observe quietly over the first week.
