Get more ropefish as they do well in groups and look good in groups. They like to do more death rolls too compare to bichirs. I currently have 14 ropefishes and sizes range from 12-18 inches. I love watching them when they do death roll. I'm planning to add some more as I'm planning to collect 20 of them, but finding a ropefish that's 12"+ is harder in my area. Most ropefish I've seen are less than 10".
