Here's why they wouldn't be a threat to neon tetras, guppies, or mollies:
* Diet: Ghost fish are primarily insectivores, meaning they eat insects and small invertebrates. They are not predatory fish.
* Size: Ghost fish are quite small, typically reaching a maximum size of 2 inches. They wouldn't be able to swallow or successfully hunt larger fish like neon tetras, guppies, or mollies.
* Temperament: Ghost fish are peaceful and shy, preferring to stay out of the way of larger fish. They are not aggressive or territorial.
However, it's always important to consider the overall size and temperament of all fish in your tank. While ghost fish are peaceful, overstocking the tank or introducing aggressive fish could lead to aggression towards smaller species.
Here are some things to consider when keeping ghost fish with other species:
* Tank size: Make sure your tank is large enough to accommodate all the fish comfortably.
* Water parameters: All fish should have compatible water parameters for optimal health.
* Species compatibility: Research the compatibility of all species before introducing them to your tank.
In conclusion, ghost fish are not known to eat or kill neon tetras, guppies, or mollies. As long as you maintain a suitable environment and compatible species, they should be peaceful and harmonious tank mates.
