Mine have trouble feeding from the surface since they are natuarally "bottom dwellers" and the danios are too quick but they go nuts over the sinking pellets I put in mainly for the cories...
Same here. I use New Life Spectrum but the majority is gobbled by my tetras before it hits the bottom. My GBR will forage afterwards and grab the remainder but will also munch on the larger sinking pellets with my cories. Same goes for my checkerboard cichlids (dicrossus filamentosus) actually. Just slower eaters by nature, I suppose.
I'm sorry yours are not doing well, bk. =(
