Vegetables and nettle for shrimp: choosing and offering them

Suitable vegetables can supplement grazing dwarf shrimp, for example cucumber, cooked carrot or spinach. Choose a small, observable addition with known origins. Vegetables or nettle do not automatically replace an appropriate feeding plan; “natural” establishes neither cleanliness nor completeness.

Prepare and observe

• Use fresh, unmouldy vegetables. Wash in clean water; use no soap, oil, salt or seasoning. Avoid seasoned leftovers.
• Soften firm vegetables such as carrot in clean water and cool completely. Cut a piece you can locate and remove. We specify no universal cooking time for all vegetables.
• Offer one kind at a time in an accessible place. Record it as added food alongside pellets, powder and fish food.
• Watch intake and breakdown. Remove remaining or deteriorating material instead of topping up a forgotten portion.

Washing or heating does not demonstrate that unknown pesticide residues have become harmless. Skip an addition if you cannot assess its suitability. Vegetables are not a necessary emergency substitute when shrimp refuse their usual food; investigate the refusal first.

Nettle: establish origins before preparation

Dried nettle is also sold as a shrimp supplement. Follow the instructions for an identifiable aquarium product. Collecting leaves yourself requires reliable plant identification and knowledge of possible spraying or other contamination. We therefore exclude unidentified plants and leaves from uncertain locations.

The cited product contains dried Urtica leaves. Pouring hot water over them may help them sink; this is not a demonstrated disinfection or pesticide treatment. Allow cooling and assess uptake and decomposition in your aquarium. Do not stack leaves because earlier additions have not disappeared.

Limits of this advice

Juveniles also require food they can reach and handle. Fan shrimp need particles in moving water and are not adequately fed by a vegetable on the bottom. A high calcium value in a plant table likewise does not prove that a piece of vegetable resolves a molting problem. For the overall diet, see choosing food.

LICG lists vegetables as possible supplements; we do not adopt a complete menu or ration from that list. The nettle source describes its own commercial product. The workflow is a cautious editorial approach, not a food-safety or nutritional-completeness test.
