I have three kribs in my 55 gallon community and they are generally peaceful. They are in with platys, swords, tetras, and kuhlis. I have as lots of hidings spots and live plants which may allow them to live peacefully with the rest of my fish. I've had the two females for about a month and just added the male today in hopes of some
kribensis fry. I understand that they get "aggressive" while protecting their territory when they're spawning but I haven't personally witnessed this (yet). Hope this helps and good luck with these beautiful fish.
