Frequently Asked Questions

Can seahorses be kept with invertebrates like shrimp or crabs?

Seahorses can generally coexist with small, peaceful invertebrates like certain types of shrimp, snails, and crabs. However, be cautious with larger or more aggressive invertebrates that might harass or prey on seahorses. Always research potential tankmates to ensure compatibility and avoid stress or harm to your seahorses.

Can seahorses be kept with other fish?

Seahorses are generally best kept in a species-specific tank or with very peaceful tankmates. They are slow swimmers and can be outcompeted for food by more aggressive or faster fish. Avoid keeping them with species that may nip at their tails or fins.

What do seahorses eat?

Seahorses are carnivorous and primarily eat live or frozen foods such as mysis shrimp, small crustaceans, and copepods. They have small mouths and require foods that are appropriately sized. High-quality frozen foods can also be offered, but live foods are often preferred for maintaining their health and stimulating natural hunting behavior.
