I'm super late on my response even though I was tagged. I never come on here ever since I don't even keep fish anymore. Are you still having trouble? If so, a month without food is no biggy at all. Everyone's given some very solid advice. Sometimes it'll take a goonch a month just to settle before even eating live. That's how it was for my first goonch. Once it's settled in, it should start taking pellets regardless if there's strong current or not. I've switched them in tanks with and without. Always used massivore cuz it's really stinky and grabs their attention pretty well. Good luck man
