Today I tried being more aggressive with the sock manager, as I was getting nowhere. Instead of passively waiting for hours by the fish tank for him to come by, only to be told, "Not gonna listen" I went to his office. I did not think he was there, so I waited outside. I saw the light go off and he exited. I said hi, and he did not acknowledge me. Up until this point, I had tried to be fairly polite, although once previously I did rather rudely say "What?" when he was staring at me by the fish tank, as he had already told me to leave and stop obsessing earlier that day. Even today, at first I tried to be somewhat polite, and tried to phrase that contrary to his assertions, the algae had not gone from his teeth, and it has been about 4 weeks,and that this forum had said that unlike his assertion, captive puffers will not chew rocks. I probably did phrase it slightly aggressively, but that is hard to avoid when you're trying to quickly tell someone they're wrong as the walk away from you without acknowledging you at all. I stopped following when we got near the fish tank, but a bit before that, I said what I had been thinking about saying for a while, thinking that perhaps I should be aggressive, since being nice had gotten me nowhere. I said, "Do you just not care at all?" He did not acknowledge me. I sat by the fish tank for a while, and saw the puffer bite a starfish on the tip of its arm, where there is now a bare white patch that was not there a few days ago. I had seen him bite the starfish once before, but the arm was touching the surface of the water, and I thought he mistook it for food. Anyway, if he can still damage a starfish, does that mean his teeth are actually ok? If not, will giving him the proper diet prevent this? I have seen him nip at the coral, for the record. Ideally, I suppose the starfish and the puffer should be separated, but I don't have a saltwater tank, and I'm afraid if I mention it to the stock manager he'll get rid of the fish and put it in bad conditions (like a tiny tank), out of anger at me (probably won't happen, but I'm concerned. He'd probably do nothing.) Actually, I'm afraid he'll put the puffer in an unsuitable tank just so I can't see it to get me to stop bothering him. Once again, this fear is based on little, as he would probably continue to ignore me, but I'm concerned nonetheless. Anyone have any suggestions, or can answer my questions about the starfish?
