Natural Aquarium Project – Freshwater Additions

Enjoy Stardew Valley with Natural Aquarium Project – Freshwater Additions, the mod that improves the game with more features. With Natural Aquarium Project – Freshwater Additions Stardew Valley Mod, you can change your gameplay to match your style. Follow our detailed guide below to know how to install and use it.

Mod Description

Adds 120 new, unique freshwater creatures and their matching tank animations for you to fish and trap for.

Adds 120 new, unique freshwater creatures and their matching tank animations for you to fish and trap for.  Weighted towards Ginger Island / late-game as I tried to stick a lot of the tropical creatures over there. While every critter is based on a real one, a lot of creative liberty was taken in some of the naming schemes, because goodness that got tricky. Also, some of these DO NOT make good aquarium pets once full grown – always do your research IRL. But this is stardew, so they stay tiny and cute.

Almost every map in SDV spawns the new fish (SVE expansion is in the works for the future), with unique creatures for every biome and season. Many of the fish are also used in other various crafting recipes in Wild Greenhouse Furniture 🙂 

See exactly when and where to find each item in the SDV Natural Aquarium and Terrarium Project Item Masterlist Spreadsheet, or have fun exploring. In general, you'll find koi in the mountain lakes, different goldfish in the town and forest river portions, bettas and other surface-breathers in the woods pond, guppies in cindersap pond, old world hard-water fish in the desert oasis, and new world cichlids / Amazonian fish on Ginger Island.

This is the last installment in the series for the foreseeable future, and the all-in-one version will be available soon, after I do some additions/cleanup to older mods in the set.

If you're looking for a similar mod in a more vanilla style, I cannot recommend More New Fish highly enough. These are more toned down and match better with my Fish Reskin or Cometkin's set


Potential Issues:

If you run another mod that adds a ton of fish like More New Fish, you should proabably download the compatibility version on the ‘files' page instead of the default one. It's a little clunky with the naming (it just adds the prefix “Freshwater” to all the items), but it should work with most or all new fish added by other mods. 

This mod adds a LOT of items, is in no way guaranteed to be balanced, and may make completing quests or challenges more difficult or impossible to complete (use CJB item spawner to complete collections, if desired).

This mod also bypasses json assets and fixes the items to ID #s directly (mostly for ease of data editing – I might migrate them to JA or DGA once it’s all dialed in), which means that objects will never be subject to the ‘shuffle’, but also that any other mod fixing objects to the same spot will be in conflict, and may cause items to disappear. Please report conflicts if you find any so I can list them 🙂

May have issues with Mineral Town, since that was reported in another set and these objects are fixed close by.
