I filled my tank this afternoon and added live sand and rock. I've seen conflicting advice about if I should use live or not. As you do I'm sat staring at the water and have spotted some critters, they look like a combination of a wood louse and slug. Anyone know what they are and if I need to remove them?
Sorry for the hazy picture, I'm using my iPhone.
