Krib.
not only are they very hardy, but they are beautifull fish with a rainbow of colours
including a reddish pink belly, an outstanding blue lining the gills, a beautifull black dash across the stomach,
a yellow outline of fins for the female and an orange for the male, and dont forget the fluorescent blue on the end of
the males spear like anal fin.
these fish are also very cute as they stay in the couple the most when two fish of opposite sex are put in tank together.
they will also react to your presence, and i find mine like to come out from the plants and bogwood when i observe the tank.
I find they are very peacefull with the other fish too.
dont mean to sell the fish to you
but are really good fish. i went through a similar thought process of you,
inbetween german blue rams, dwarf cichlids and kribs. do not regret even a bit my choice.
