I think it's probably the salt too. I have had a pleco for 4 months now and until about 3 weeks ago never ever feed him anything. I have a little fake wooden cave in my tank and  he is always in there during the day cause they are nocturnal animals you know. Maybe you should get a small cave for him to hide in during the day. Mine now gets fed spirulina and algea wafers and he is doing really great. He doesn't seem to like algea in my tank at all. I don't know maybe he's just a weird little pleco. He seems to like my driftwood too at night that's where he goes. Try adding some more decor to your tank and see if that helps out any. ;D Good luck.
