I have the chance to buy either 5" hi-fin red wolfs or a 7"common wolf(mala) I currently have a 96x20x24 tank with 2 FX5's and a rio2500 for water circulation current stock list is a 7" orino, 5-5" peru monos, 4" marbled pim, 7-8" spotted gar and a 5" long fin albino oscar. Current decor in the tank is 3 vertically placed pieces of drift wood and black sand. I will be keeping the tank fairly basic for maintenance purposes as I had recently changed it from a fully planted tank. BTW lighting is 2 hanging 48" GLO dual T5 HO fixtures. Tank is very well fed with feeder rosies as I get an amazing deal through a wholesaler and all fish are in great health with no diseases or problems.
