Do Angelfish Eat Shrimp? A Detailed Look at Their Compatibility

As an aquarium hobbyist, I love keeping both angelfish and shrimp. Their colors and behaviors liven up any tank. However, I’ve learned the hard way that these two beautiful creatures don’t always mix. So, do angelfish eat shrimp?

The short answer is yes, angelfish often view shrimp as food and will readily eat smaller shrimp species. Their predatory instincts and shrimp’s small size make cohabitation risky. However, with proper precautions, some shrimp species can successfully live with angelfish.

In this article, I’ll share my experience and research on angelfish and shrimp compatibility. I’ll cover:

• Angelfish’s natural behaviors and dietary needs
• Ideal tank conditions for both fish and shrimp
• Which shrimp species are most vulnerable
• Tips to potentially keep them together
• How to safely introduce shrimp
• Best tankmates for an angelfish/shrimp tank

Let’s take a detailed look at how to avoid making shrimp a snack for hungry angelfish!

Angelfish’s Predatory Nature

Angelfish are cichlids native to South America In the wild, they are opportunistic predators that eat small fish, insects, and crustaceans Their natural behaviors include

• Foraging along river bottoms for food
• Ambushing prey from dense vegetation
• Establishing social hierarchies and territories
• Guarding bubble nests of eggs

This predatory background carries over into the home aquarium. Angelfish readily eat live foods including brine shrimp, bloodworms and small feeder fish. Their size and powerful jaws allow them to consume much smaller tankmates.

Shrimp’s Vulnerability

Freshwater shrimp, on the other hand, are largely peaceful scavengers. They spend hours grazing on algae and biofilm. Most species remain under 2 inches long, making them vulnerable to predation.

Dwarf shrimp like Cherry and Bee shrimp only grow to around 1 inch. Their bright colors and constant movement easily attract angelfish attention. Larger shrimp species can reach 2+ inches but still face moderate risk from angelfish.

When sensing danger, shrimp dart rapidly to shelter. But this movement can trigger the angelfish’s prey drive. Hiding spaces and plants offer some protection, but shrimp inevitably venture into the open to forage.

Ideal Tank Conditions

Angelfish and shrimp also require different tank conditions to thrive:

Temperature: Angelfish prefer 78-84°F while shrimp do best from 68-78°F. Fluctuating temperatures can stress both.

pH: Angelfish thrive in pH 6.5-7.5. Shrimp need specific ranges depending on species, often lower pH.

Tank size: Angelfish need at least 29 gallons for a pair, shrimp can thrive in 10 gallons.

Plants/decor: Angelfish prefer open swimming room. Shrimp need dense planting and hiding spots.

Filtration: Angelfish produce more waste, needing stronger filtration than shrimp.

Lighting: Angelfish tolerate moderate light. Shrimp prefer low lighting with lots of shade.

Maintaining conditions suitable for both can prove challenging. Compromises may negatively impact either species.

Most Vulnerable Shrimp Species

Based on size and care requirements, these shrimp species face the highest risk from angelfish:

• Cherry shrimp: Max size around 1 inch, bright red color. Require stable, slightly acidic water.

• Crystal red/black shrimp: Only reach 1.5 inches, need pristine water conditions angelfish can’t provide.

• Bee shrimp: Tiny and brightly colored like their namesake. Require acidic, mineral-rich water.

• Caridina cantonensis: Sparse swimmers, grow to 1.5 inches. Need highly oxygenated water.

• Snowball shrimp: Pure white color catches angelfish attention. Max of 1.5 inch size.

Larger shrimp like amanos (2 inches) and bamboo shrimp (3 inches) might withstand angelfish better. But they still face moderate predation risk.

Tips for Potentially Keeping Angelfish and Shrimp Together

While difficult, experienced aquarists may have success keeping angelfish with select shrimp species. Some tips include:

• Choose the largest shrimp species available – at least 2 inches size.

• Provide tons of hiding spots with plants like Anubias, moss, cholla wood, caves, etc.

• Arrange hardscape to break sight lines and create visual barriers.

• Feed angelfish well with protein sources like bloodworms.

• Use a 40+ gallon tank to create space and territory between them.

• Add the shrimp first, allowing them to find the best hiding areas.

• Monitor during feedings for any signs of aggression.

Even with these precautions, predation attempts will likely occur eventually. Well-fed angelfish may ignore adult shrimp but eat all babies.

Introducing Shrimp to an Angelfish Tank

Here are some best practices if attempting to add shrimp to an established angelfish tank:

• Do a 30-40% water change before adding shrimp to ensure clean conditions.

• Turn off tank lights and introduce shrimp at night when angelfish are less active.

• Acclimate shrimp slowly over 2-3 hours. Float bag to equalize temperatures before starting.

• Immediately after adding, feed the angelfish to distract them from new arrivals.

• Check every couple hours overnight. Remove any angelfish showing interest in the shrimp.

• Be prepared to remove shrimp if signs of stress or aggression occur. Have backup tank ready.

Even with precautions, shrimp losses should be expected. Never leave new introductions unattended for long.

Suitable Tankmates for Angelfish and Shrimp

When trying to keep angelfish with shrimp, choose peaceful community fish that won’t become expensive shrimp meals. Good options include:

• Small rasboras
• Corydoras catfish
• Otocinclus catfish
• Hatchetfish
• Tetras
• Dwarf gourami
• Bristlenose plecos

Avoid fin nippers like barbs, aggressive cichlids, large loaches, and other shrimp eaters. Stick to nano schooling fish that largely ignore both shrimp and angelfish.

Overall, angelfish pose a significant threat to shrimp, especially smaller colorful varieties. Their differing needs also make cohabitation tricky. While possible in very large, densely planted tanks, shrimp losses should be expected.

For best results, I recommend keeping angelfish and shrimp in separate tanks. This allows tailoring conditions to each species’ needs and prevents expensive shrimp casualties. However, with vigilance and contingency plans, an angelfish/shrimp community can potentially work short-term.
