I'd watch him closely and get some salt in that tank asap. Never a good sign when a plec that is known to hide doesn't hide. Back when I didn't know better, around 6 years ago, I got a king tiger because he didn't hide in the show tank, and he died a couple days after I got him home.
will put salt in the tank as I type. It has been three days, since it has been in the tank, eats bloodworms like crazy and trying som cucumber tonight
