Why You Need Snail-Eating Aquarium Fish
Snail populations in aquariums can do a lot of harm to your ecosystem. When they are not controlled, snails cause expensive damage because they eat plants and algae species which provide food for the fish fry. In addition to looking unsightly, the snails leave behind mucus that harms various aquatic habitats including water clarity. Even if you have supplements that contain snail control compounds when overzealously applied, it will be problematic since many snails don’t respond to the anti-cavitation chemicals.
The introduction of snails can cause problems with fish and plant health as well as your aquarium greenhouse environment. When you have a lot of snails, it means other microorganisms will reduce in number so living conditions in your aquatic world would be tainted from any point around.
What Aquarium Fish Eat Snails?
