Snow black clam
Snow black clams are beneficial for aquaria, they are like living filters that help keep aquarium water crystal clear and clean. They can filter out uneaten food and detritus from the water as these Freshwater Clams help to maintain water quality and lower nitrate levels naturally.
Usually shipped about the size of a half dollar to a silver dollar, you will NOT be disappointed! You do not need to feed them, they are filter feeders, and they will feed off micro-organisms and waste in your aquarium substrate! When you first get them, they will need to acclimate as you would any other new fish, drop them in your aquarium, and gently push them just a touch into your substrate. They prefer to bury themselves in “small” gravel or sand substrates, so no larger- sized rock substrates, however we have kept them for decades in old tanks that had fairly chunky rock and they did well. They will move around on their own, and will NOT disturb your plants or their roots.
For aquariums: stock about 8 snow black clams per 1 sq foot of gravel bed space.
