500 Nassarius Vibex
Excellent sand stirrer and scavenger. These snails will pop out of the sand when they smell food, or when you are feeding the fish. Contrary to popular belief these snails do NOT eat algae; they eat detritus and leftover fish food. They are still good in your tank though, because they will help maintain your nitrate levels, and clean some of the debris that is building up in your substrate.
These snails are almost a must for those of you with messy eaters, such as predatory fish and seahorses. They are also good to have around if your fish are well fed.
They grow to about a half of an inch tall, and 3/5 of an inch in length. A decent sized snail. Combining them with our Cerith and Dwarf Planaxis Snails is the best way to get your substrate clean.
Lot of 500.
