How to use these fish & index guides
Fish Guide explains the roles of a catch: the completed attempt, a collection entry and a pet you want to keep. Fish List gives recognizable tutorial names and a way to read the wider index. The index guide then focuses on choosing the missing species that makes the next trip useful.
For a longer collection project, use Complete Fish Index to organize reachable goals and the character progression needed for another depth. Rare Fish separates deeper discovery, mutation bonuses and aquarium evolution. The sea-monster capture route gives a new creature attempt a clear beginning, result and pet or collection follow-up.
