Hi there i plan on this weekend being a time where i can finally start my first dart frog viv!!.... it is a 18x18x24 medium size glass Exo-terra! I am really inspired by all the great looking vivs out there! i would like to use GS and make a water feature! However im wondering if since this is my first i , if i should spray the GS on the glass or use a thin layer of styro foam board? Also if anybody has any ideas on a dart frog viv that would work good in this tank i would love to know!

Thanks
