If you've ever found yourself standing in front of a tank of tiny guppy fry, wondering what on earth those adorable little creatures eat, you're not alone. These newborn fish require a bit of extra care and attention to grow into the vibrant beauties they are meant to become. Let's dive into what baby guppies eat and how you can best meet their nutritional needs.

Newborn guppy fry are different from adult guppies not just in size but also in their nutritional requirements. With high metabolisms and tiny stomachs that need frequent fill-ups, feeding these little swimmers 4 to 8 times daily is a must. Remember, their stomachs empty every 20 minutes!

High-Protein Foods for Growth

To promote healthy development, ensure you're providing high-protein foods. One popular option is high-quality, high-protein flake foods that can be crushed into a fine powder. Offering them just before lights out is a convenient feeding strategy, as it mirrors their natural nocturnal feeding habits.

Top High-Protein Options:

  • High-protein flake foods (finely crushed)
  • Baby Brine Shrimp
  • Egg yolk paste

Live Food Delights

Live foods are the gold standard when it comes to feeding guppy fry, offering both nutritional benefits and stimulating their natural hunting instincts. Baby Brine Shrimp, also known as BBS, tops the list. They are packed with essential nutrients and are the perfect size for guppy fry. Ensure you choose baby versions, as adults are too large and less nutritious.

If you're looking for alternatives, microworms are an easy-to-culture live food that supports swift growth, while vinegar eels offer a great option for very tiny fry.

Adding Variety: Other Food Sources

To avoid monotonous meals and provide balanced nutrition, consider incorporating other sources like Daphnia or even a carefully prepared egg yolk paste. But remember, moderation is key—feed just enough to prevent excess waste and potential water pollution.

Here’s a quick comparison to guide your choices:

Food Type Nutritional Benefit Ease of Use
Baby Brine Shrimp Highly nutritious, promotes growth Moderate (requires hatchery or purchase)
Microworms Rich in protein, easy growth Easy (self-cultured)
Egg Yolk Paste Protein-rich, easily digestible Easy (homemade)

Environmental Tuning for Optimal Growth

Frequently Asked Questions

What do you feed baby guppies?

Baby guppies can eat specialized fry food, finely crushed fish flakes, or newly hatched brine shrimp. You can also feed them small amounts of blanched vegetables like spinach or peas, and even live or frozen foods such as daphnia and bloodworms for a varied diet. Ensure the food is small enough for their tiny mouths.

How often should I feed guppy fry?

Guppy fry should be fed small amounts of food 4 to 6 times a day to support their rapid growth. Once they grow a little older, you can reduce feeding to 2-3 times a day. Avoid overfeeding to maintain water quality in the tank.

Can guppy fry eat vegetables?

Yes, guppy fry can eat blanched vegetables like spinach, zucchini, or peas. These should be offered in tiny, softened pieces that are easy for them to consume. Vegetables can supplement their protein-based diet for balanced nutrition.

How long does it take for guppy fry to grow?

Guppy fry typically take about 6-8 weeks to grow large enough to be introduced into a main tank. Proper feeding and ideal water conditions can help speed up their growth. Separate them from adult guppies until they are big enough to avoid being eaten.

Can I keep 1-day-old guppy fry with adult fish?

It is not recommended to keep 1-day-old guppy fry with adult fish as they are at risk of being eaten. Instead, place them in a breeding box or a separate tank until they grow big enough to coexist safely.
