The Striped Raphael Catfish or Chocolate Catfish are a good, peaceful community fish. They are friendly with nearly all other community tank mates. This includes various loaches (Yoyo, Zebra, Clown), Cypriniformes (Bala shark, Red-tail shark), and schooling fish (Tetras, Barbs) that don't stay too small. As is a fact with life, larger fish may eat the smaller fish...
Just make sure you have adequate housing for the Striped Raphael, as it can grow up to 8 inches!
