Hello everyone just joied the site today. I started to collect aggressive fish about a year ago. I have 3 Oscars 1 Red and 2 Tigers about the size of my hand in a 55 gallon corner tank. I also had a red bellied Pirahana that just past away due to a bad batch of feeders he got real sick real fast and could not bounce back. RIP Goober that is why i joined this site i was browseing the internet looking for a new and exciting fish to keep. So any suggestions there would be great. looking forward to talkign with everyone
