So i posted this topic on another forum and not one responded. So here it goes; i purchased a new tank and trying to figure out what to do.... i have a 75 with all my fish in it right now and a 55 cycling.. basic fish are 3 blk calvus, 4 ocetallus golds, 1 pulcher (tangs)..., 1 yellow lab, 2 lab hongi, 1 red zebra, 1 Sciaenochromis fryeri (malawi). just wondering what would you do have so many ideas (species calvus, 55 shellie tank......) just thought one or two thoughts might help me decide. thanks for all who reply
