We evaluated the survival and growth of 3‐d post‐hatch Siamese fighting fish, Betta splendens larvae, raised during 15 d in salt‐free or salt‐added freshwater (5 ppt using common table salt) and fed with a sequence of traditional live diets ( Chlorella sp., rotifers, and Artemia ) or with one formulated diet complemented with a single or daily additions of Chlorella . The highest survival were those of natural‐fed larvae, at 5 and 0 ppt (100 and 96.67 ± 5.77%), and there were no significant differences in final length and weight, although these were more variable in the case of the larvae maintained at 5 ppt. The use of table salt had a negative effect on the trophonts of the external parasitic dinoflagellate Piscinoodinium sp., which colonized the body surface of the larvae raised at 0 ppt and were absent on those kept at 5 ppt.
