While moving the tank, i cut the DoOdOo out of my finger on some broken glass...
HoWDiDALLthisGLASSgEtINMyTank ???
moral of the story is- i took all the glass out and it was properly recycled. BUT NO FISH WERE HARMED by the glass (well maybe one but it coulda been another fish that did it) only my poor finger.
So ill go with yous guyses advise and make a big decor nextime out of smoothedge bottles that are silicon'd together for easier removal/installation.
