Thank you Scott. I have my enclosure split into 2 with a piece of plexiglass. I have a filter in the water so I do weekly water changes of about 50%. I got the rocks from my neighbour, he was doing a big chiclid tank and had tons left over. I believe he got them from work, they never went into the fish water and even though he said he boiled them I did it again to be sure. Maybe im just stressing.
