rock landscape

[Aquamarina]

Hi. I am looking for some advice re: re-laying the rock in our fish-only tank. Our cowfish is not the right shape for sliding in and out of the crannies we currently have in our wall tank, which is 3' deep by 6' wide, open on one side only. He has been stuck 4 times in the last year, causing a lot of anxiety and work to get him free. Apollo has never learned, apparently, to swim backwards or to plan ahead. After the last session, I am seriously considering offering him to a good home (which we are reluctant to do as he is the most personable member of the tank), or discovering whether we can get some lighter, more movable rock. Our current rock is red lava rock, I think, and is quite heavy.

My question is whether anyone can recommend someone who would lay some different rock for us.

I will try to attach a photo of Apollo in one of his predicaments. This situation occurred on the inaccessible side of the tank (where I can't even clean the glass well), and it took 3 of us (2 for relaying messages to the operator who couldn't see what he was doing) about 2 hrs to free him by chipping at the rock with a steel metre stick. During the time, we were not only anxious about his welfare, but hoped to goodness he wasn't going to release his toxins! [img]

Thanks.
