I've try'd feeding @ night also ,the day it came to store we got it so I don't think it ate thereMight be still settling in. Will eventually eat. What was it eating at the lfs? Try night feeding?
I have a tiger s/nose catfish,2x datnoides,2xearth eater chiclids(not sure if its the wright name),3xpolyputres(bicher),2xupside down catfish,silverish like gar,mono,2 x basic gerumies,black/orange shark like fish and a crown loach (mind my spelling)What are the tankmates? Sometimes a busy tank with other fish will make 'en nervous and not want to eat in the beginning. I've seen them take a week to start eating and get used to the tank. Try earthworms and tilapia. May need to target feed as well. But I think just be patient and wait.
You have a lot bottom competition in your tank, it will need time to establish to new environment, If you have a cave for it to hide in then it will adaptI have a cave,he also burries himself in the gravelYou have a lot bottom competition in your tank, it will need time to establish to new environment, If you have a cave for it to hide in then it will adapt sooner.
