Hey guys, I recently bought a 44 Gallon tank from a friend who didn't want it anymore, and it came with 2 fish, 1 is a type of plecostomus, and I'm not sure what the other is, I was hoping you can tell me, I've had him for a week, and he is currently housed in an overcrowded 20 Gallon (the 44 gallon tank is still cycling), He does not seem to be eating, but I've had him for over a week and he's still alive and looking healthy, as well as getting along with other fish. if anyone can tell me what type he is it would be appreciated. he is about 7 inches long, let me know if you need more information
