For the longest time i housed my male eastern mud and female razorback musk together, the got along quite well, but this past winter my razorback passed away from some disease that took action before i did. Ever since then my eastern mud has not had the same eating habits, as he was once a hog on the reptimen sticks, he wont touch him, and only sometimes will eat the feeder fish

Help! if someone has an idea what to do that would be great
