I recently purchased a PBT from my LFS and I noticed a wierd behavior within hours of putting him into my tank. He appears to be rubbing his dorsal fin on my LR and on the sand sometimes. What is he doing/ should I be concerned? In my paranoid state, I thought that he may have a parasite but I have looked at him very carefully and have not noticed any discoloration or white plaques which would indicate ick . . . Please let me know what you think.
Thx,
Steven
