He was my first ray and I had him for about 4 months. I had put a LOT of effort into getting him to eat initially, some of you on here are to thank for your assistance in that. He started putting on weight very well and was doing fantastic. About a week after the incident with the filter media, the others started acting so much better and he went from being fine to very bad. I'd almost compare how he acted to having a stroke. Regardless, he continued to worsen and today was the end. The two hystrix are doing incredibly well and I hope they continue to do so. RIP Flappy
