That is a really nice tank and a good price too.
I have larger rock in my tank too. I witnessed my orange cap oranda choking one day. She had a piece of gravel lodged in her mouth and couldn't get it out. She was panicking. I grabbed the net and scooped her up to try to help and the rock dislodged in the process so then she was fine. It can and does happen. Large rock or no rock is best with goldies.
