Wow, don't sign on for a few days and all this! We did split the rock, but only at the end, it has a club thing on one end and being the way the rocks are situated it made it hard to place in the tank, it's worked out well and we only broke off the area that didn't have any zoo's on it, still wish we had a bigger tank, but that's way down the line, the 29 will have to do for now and we are finished with adding anything unless we find some blue zoos which we really want and then we will be done. Now the fun part watching everything grow and cover, the zoo's are very hardy we found, even some that were broken off when we got them and aren't attached to anything yet are still living as they have settled into the sand. Thanks for everyone's help!
The piece we broke off is to the right with the orange zoo's placed on them, the break worked where we placed it created more of a cave for our cleaner shrimp the piggies of the tank, they love it and we are happy with it too!
