I have a 55 gallon tank with alot of hiding and plants. I currently have a 4 inch female JD, a 1 inch tiger oscar, pictus catfish, and two clown loaches. would an electric blue jack dempsey do well in this enviroment? The main thing im worried about is the larger jack. she usually isnt aggressive at all but i dont know if i can trust her with a near 30 dollar fish. Any advice is appreciated
