I've been keeping Kribs and Corys together for years without issue. I don't see a problem with doing so.N0body Of The Goat said:I would not risk a Krib pair with corydora (possibly mature related Brochis) or "Kuhli" Loaches (I say "Kuhli" because what most think of as that species are often Pangio semicinta, not Pangio kuhli), adult Zebra Loaches would probably be ok as would the Bleeding Hearts, Angelfish, BN Plec.
