Hey every body. I just picked up a rose queen from the LFS 2 days ago and was wondering if anyone could help. He is in a 55 gallon aquarium and he keeps on digging. the other day he was digging and he made the rock collapse that I had stacked. I removed alot of tthe lace rock and there are now alot of open spaces. I was wondering what to use as cover that would be alot safer. I was thinking about using large PVC pipe for him to hide in becase he seems to like caves. Any ideas are very appreciated.
