First time fish keeper. Just set up new tank for first tim with 6 Danios. Shop sold me NTlab probiotic food - saying feed 2 ‘pellets’ per fish every 2 days. But the ‘pellets’ are minuscule grains. Almost impossible to Count out 12 ... and don’t seem nearly enough to feed all 6. Does anyone have experience with this food? Is that correct? Don’t want to starve the poor things - but I’m aware it’s easy to over feed. Thanks in advance for any advice
