So, a commonly told rule of thumb is to feed your fish "the amount that they can consume in 3 to 5 minutes".
Though, I don't think this rule can apply to Danios because of how fast and aggressively they eat. Watching Danios is like watching regular fish in fast forward on your dvd player. And if you have Danios, you probably would agree.
So, how much do you feed your Danios? Do you change the rule to "the ammount that they can consume in 90 seconds"? Or what?
