* Diet: Seahorses are primarily carnivores, while starfishes are mostly scavengers or filter feeders. This means their dietary needs are very different, and a tank designed for one might not suit the other.
* Water Parameters: While both species are marine, they have different water parameter requirements. Seahorses are generally more sensitive to changes in salinity and water quality.
* Space and Behavior: Seahorses are active swimmers and need ample space to move around, while starfishes are more sedentary. This can lead to conflicts as seahorses might accidentally injure or even consume smaller starfish.
* Substrate: Seahorses prefer a sandy substrate for their tank, while some starfish species thrive on a rocky environment.
In short, it's best to keep these species in separate tanks to ensure their health and well-being.
If you are looking to keep both seahorses and starfish, consider setting up two separate tanks with appropriate conditions for each species. This way, you can provide them with the best possible care and enjoy their unique beauty.
