So i'm finally going back to school this weekend to begin cycling my 36g bowfront for the new semester. I bought a powerfilter rated for a 55g, a power head and some live plants with my summer earnings and i'm gonna be using gravel and filter media from a previous tank to kick start the cycle. The fish i want to stock the tank with include: 2 keyhole cichlids, 1 polypterus delhezi, 3 pimelodus pictus, and 1 royal plecostomus. My question is: would this work? and i'm not sure on the royals adult size but if its gets too large id be fine with a smaller pleco. Also ive never kept bichirs so i was wondering what a balanced diet would include (i was thinking predator pellets and frozen brine shrimp)
