I have kept a lot of fish but never an american flagfish. My wonderful local LFS has a tank full of them for the first time I've seen and I'm curious if anyone has any insight into how they might fit into my 55 gallon community tank. I've read about them and opinions are all over the place. My tank is 8 plus years old and has experienced some attrition just due to the age of the tank. It has hatchets, cories, harlequins, rummies and a few glass cats - all peaceful but quite active despite being older fish. I'm curious how they they might fit in and how large a group would be ideal. I have other tanks but they are all full of SA cichlids that would have them for lunch, so no backup plan is available outside of a quarantine tank. Thanks!
