How many crabs shoud I have in a 20 gallon aquarium. I have 2 clownfish and a green brittle star in it. I also have 15 pounds of live rock. I was just wondering what a good number of crabs would be?
haha, i knew you'd make a comment about the color of the star, reefscape thanks to you i know to stay away from the green ones, which is a good thing to know as i'm a sucker for critters that are colorful. i'd be really sad if i woke up one day and my star had eaten my beloved blood shrimp...
