Fish were once again the subject for the fifth definitive stamp series. Increasing stamp production costs, and lack of need for very low values due to high postal rates set the lowest value at 15c. However, the highest value was decreased to $3.

The set was originally scheduled for release on July 1,1992, but a spelling error on the 45c value was discovered after the stamps arrived in Tuvalu. Part of the scientific name was misspelled coxozonus instead of loxozonus. The set went on sale on July 15 after the corrected reprints arrived. It is unclear why the original error stamps were never destroyed. Some were used for the 1996 Taipei stamp show overprints. It is still unclear on who printed the overprints. However, non-overprinted stamps with the spelling error have been seen mint and used, but are scarce.
