th volcano is nice but that takes up a ton of otherwise usable water space/bottom area.
am i the only one who thinks this? unless the mountian is used to house the filter equipment, which seems plausable
That particular setup is based around the amphibious crabs that the owner keeps in there; said crabs need to come out of the water from time to time hence the volcano which has pools and streams and also disguises all of the intakes and such.
