I got my rubber mouth pleco from Petsmart about 4 or 5 days ago. Since then he hasn't been eating much. The tank is quite new so there is alsmost no algae there. I've tried to give him blanched broccoli and carrot but he won't touch them for some reason. Is there any ways I can get him to eat? He is quite shy, spending most of of his time under a couple of driftwood pieces I put in the tank. Also, do you guys happen to know how big a rubber mouth pleco would typically get. I wasn't going to get him but the shop assistant told me that he wouldn't grow bigger than 10 inches. I tried to look up but not much to see since I don't know their scientific name...
