* Different water parameters: Allergy eaters generally prefer slightly cooler water than molly fish.
* Feeding habits: Allergy eaters are primarily herbivores and will eat algae, while molly fish are omnivores and require a more varied diet.
* Aggression: While allergy eaters are generally peaceful, some species can become aggressive, especially towards smaller fish like mollies.
* Size: Some allergy eaters can grow quite large, which can be intimidating to mollies, especially if there's limited space.
Instead of mixing them, it's best to choose fish that have compatible needs and temperaments. For example, consider these compatible tank mates for mollies:
* Other livebearers: Guppies, swordtails, platys
* Peaceful tetras: Neon tetras, cardinal tetras
* Dwarf gouramis: These are generally peaceful and come in a variety of beautiful colors.
Before adding any new fish to your tank, it's always a good idea to research their needs and ensure they are compatible with your existing fish.
