Can I buy fish on this website?

No. Fish exist only inside the Roblox experience. This page is a lookup of published names and reported prices.

Is the $100 pack confirmed in-game?

It is printed on a community fish page. I did not open a pack in the client on 13 October 2026.

Where do the other pet names live?

The community lookup contains 89 names across seven families, with reported rarity, unlocks and the 16 remaining unnamed slots.

Pet Store Tycoon fish and aquarium pets

Community instructions start at the tutorial tank: purchase a Fish Pack, open its cards and choose Keep for the fish you want to retain. The reported pack costs $100. Below are all 14 names in the checked community catalogue, not an official full list.

Published by petstoretycoon.xyz editorial desk.

The official thumbnail establishes neither prices nor a catalogue. The fish lookup and $100 pack figure come from attributed community pages; a wiki also gives broad tank-price estimates without sufficient model-specific evidence. These reports are not this site’s purchases or a current price quote for every aquarium.

What the write-ups agree on

Fish are described as the first pet family in the 2026 remake, available without a level gate.
They need their own aquarium, water upkeep, and matching shelf goods. That care note is from community guides, not from the badges API.
A fish pack is listed at $100 and is described as giving three random fish.
A community page says the fish catalogue has 15 slots and 14 known names. This page does not invent the fifteenth name.

Prices I am not going to guess

The community fish table reports worth of $25 for Goldfish, $150 for Tiger Muskellunge and $1,000 for Leviathan Hatchling; worth is not necessarily a completed sale price. The wiki’s broad aquarium-price estimates do not establish a verified price for a particular model, and no current Exotic fish-pack Robux price was independently obtained. Marine Life is a later water family, not the starting Fish Pack.

From the starting tank to a cared-for fish

Follow the starting aquarium tutorial and read its pack offer. The community catalogue reports the Fish Pack at $100.
Open the pack’s cards and select Keep when offered; the exact fish is a random result, not an individual-species purchase.
Place a kept fish in an appropriate available aquarium according to the client’s prompts.
Use the enclosure’s feeding and maintenance controls and keep matching care products stocked. Device controls, supplies consumed and aquarium upgrade prices have not been tested here.

The whale teaser is not a fish list

As of 13 October 2026, Something Lurks Below... is scheduled from 10 to 17 October. Its official tagline describes adding a basement ocean for marine life beneath the store. That is a feature announcement, not a fish species list or a completed gameplay test; it is separate from Halloween. See the event timeline.
