i am gonna make this.. but i will make mine smaller and with a back to make it a cave.
my question is if i use hot glue to bond the two pieces is that bad ????
also how long does java moss take to grow.
about the hot glue, it doesn't seem like it would fare too well when submerged, here's a thread addressing the same question: http://www.aquariacentral.com/forums/showthread.php?t=26254
As for the java moss I assume it all depends on your setup. It's listed as a very slow grower on the planted tank and I've read that it takes months for peoples' moss walls to grow in. Sorry Ican't tell you from firsthand experience as this is my first planted tank: the moss wall is just over a month old and the arch are less than a week old.
