The time at which neon tetra can be weaned from live food to formulated feed had not been previously established.
Moreover, early weaning induced a high mortality. Weaning at a larger size improved the survival rate but
temporarily lowered fish growth after the transfer of larvae to a dry feed. Considering the poor growth rates obtained
by offering the fish dry feed from hatching onwards, it appears more appropriate to feed the newly- hatched larvae
with live organisms or mixed diets (live + dry foods) up to a developmental stage allowing successful weaning of
the larvae with dry feed. In that respect neon tetra fry previously fed with mixed zooplankton for one month were
weaned to dry formulated feed.
