My leather is mounted on a small rock and that I placed in the sand. Not sure if thats a good thing but it has doubled in size so something must be ok.
I will be getting into fragging very soon, as most of my zooas are obscenely large colonies now. i figure I'll frag the easy ones at first and put them in my new 20g tank I got today.
Check out craigslist. theres a ton of people near me always selling frags for like $10.
