Yep boiling them does help a little bit, but doesnt usually fully sink them. This piece has been in this tank for ages and it was sunken, but i took it out a few weeks ago when re-arranging some fish, and never bothered to put it back in so i let it dry out a bit. It wont take long for it to sink again....
All the tanks now have fish in them, but most are just on holiday whilst there 'homes' get built Im going to rotorua this weekend, and im gunna have a bit of money to spend so will hopefully come back with something exciting
Heh, yer, you could call it that
Its sitting there pretty firmly. What you cant realy see in the pic is the flat top on the DW just where its sitting, and also its a very flat rock.... IMO, if it fell, it wouldnt be big enough to cause any damage anyway....
