i have a 7-8 inch white tip wolf fish in a 50 gallon tank by him self right now, hes been in there for about 2 weeks and is doing really well, even got him to take some pellets. but the tank is kind of boring so im wondering if there were any fish i could add in there. i tried a 6 inch jag and they were constantly fighting usually with the jag on the losing end but i noticed the wolf fish would only attack the jag when he would attack him. if the jag would just swim by there was no reaction. so any suggestions are welcome
