* Size Difference: Rope fish, also known as "eel loaches," are much larger than zebra danios. Even the smaller species of rope fish are significantly bigger than zebra danios.
* Diet: Rope fish are primarily bottom feeders and prefer worms, insects, and crustaceans. While they might occasionally take small fish, it's not their usual diet.
* Habitat: Rope fish prefer slightly cooler water temperatures than zebra danios. This means they're not likely to be in the same environment together.
However, it's important to note:
* Individual Variability: Some individuals of any species can be more aggressive than others. It's possible, although unlikely, that a particularly large or hungry rope fish might try to eat a zebra danio.
* Tank Size: If the tank is very small, the rope fish might feel pressured and may attempt to eat anything that moves, including the zebra danios.
In general, it's best to avoid putting rope fish and zebra danios together in the same tank. This will ensure the safety of both fish species.
