I tried bloodworm pellets for my corys... they totally ignored it... the pellets just broke down into a mess and clouded the water... my fish (spoilt?!) only eat: frozen bloodworm, spirulina wafers, a bit of flake (but this is only if they're really hungry)... and sea monkeys (brine shrimp)... they'll all have a go at cooked, shelled pea halves and blanched cucumber or courgette...
