cool, thank you.. I was starting to pace a little..... they have a barrel they love sticking their heads out of, two tunnels and a castle gate that has a tunnel and holes through it that they clamber into..... they hide behind the two plants we have, and ive been doing 30% water change everyday since ammonia problem started up... hopefully with the new filter and the addition of bacteria that should soon ease up... (tank hasnt cycled yet!!)
