Panchax are great if you want thugs that eat all fish smaller than an adult platy.
How about Chela Dadiburjori? They are easily available but dont sell well, same as a lot of beautiful species! We caneasily get hold of them but whats the point if they dont sell!>
They are small as/smaller than danios, surface dwelling, have little upturned fins like hatchets, shoaling and 100% gentle (mor so than most danios!)...
They have to be in a nice tank to colour up, but once coloured up, a lovely shade of yellow with metallic blue strip/dashes and dots down the sides.
