I am a new person coming into this hobby. I hve a friend who helps me and guides me since he has kept these fish for a long time. I would like to seek some more help and I heard that this website is a good one. I have a silver arowana around 1foot and 5 or 6 inches, a peakock bass around 8-9 inches and a siamese tigerfish that is around 6-8 inches. I would like to know what other fish I can keep in this tank and also some recomendations for fish that are exciting to keep. I am at a intermediet level so i can keep some harder fish to maintain. Thank you very much! BTW I am 12
