This can lead to a situation better know to fans of big predatory tropical
Catfish and the like.
Feeding like this can lead to cyclical high ammonia and nitrite levels, as
the filter bacteria are having to try to cope with semi-starvation one day,
just prior to a feed, and then overload two days later as the fish begins to
excrete the ammonia produced from the digestion of all that protein (plus
maybe some amount of poorly-digested food in the faeces).
Better to feed smaller amounts at shorter intervals if possible, this will
even out the production of ammonia to a level where the filter bacteria can
deal with it quickly.
