Fisch, the fishing game on Roblox, is teasing a new companion system that introduces collectible creature pets, including shark models and what appears to be a baby Megalodon. The feature has been previewed by content creators ahead of its arrival, but the developers have not yet locked in a public release time.
Quick answer: The companion update for Fisch has been previewed but not officially released. No confirmed launch date or time is currently available.

What the companion update adds
The update centers on small creature companions that follow your character around the map. Previewed designs include shark-themed companions and a baby Megalodon model that has drawn comparisons to the "Jeff the Land Shark" style of cute predator. Additional skins tied to the system have also been shown.
The companions appear to be themed around different islands in Fisch, suggesting that obtaining each one will be tied to specific in-game locations rather than dropping from a single source. How they are unlocked, whether through quests, exploration, or RNG-based mechanics, has not been confirmed by the developers.
How companions may be obtained
Based on previewed footage, companions look connected to the existing island structure of Fisch. The baby Megalodon model has been speculated to come from Meg eggs, though no official drop method has been published. Customization options such as attaching gear to companions have been discussed by players but are not confirmed features.

Release timing
The companion content has been shown in preview videos and scheduled livestreams, but the Fisch development team has not posted a confirmed release date and time for the update itself. Until an official announcement appears in the game's communication channels, exact rollout timing remains open.
Players who want to be ready can make sure their account is current with the most recent Fisch update, since companion features will likely require the latest game version. The game itself is available on the official page on Roblox.
How this fits with the current Fisch meta
Fisch's most recent major content drop was the Wrath of Olympus update, which added six layered zones tied to Greek mythology, including areas themed around Apollo, Poseidon, Zeus, and Hades, plus the Olympian Fisher endgame layer. That update introduced exclusive rods such as Bologona's War Axe, Apollo's Sunshot, Poseidon's Lance, Zeus's Thunder, Hades Soul Scythe, and the Olympian Godbreaker.
The companion system looks like a separate progression layer rather than a replacement for rod hunting. It adds a cosmetic and possibly utility-based collection loop on top of the existing fishing, hunt, and bestiary mechanics.

What to watch for at launch
| Detail | Status |
|---|---|
| Release date and time | Not officially confirmed |
| Companion list | Partially previewed (sharks, baby Megalodon, additional skins) |
| Acquisition method | Likely tied to islands; specifics unconfirmed |
| Customization (gear, etc.) | Not confirmed |

Once the update is live, the in-game UI will be the most reliable place to verify which companions exist, how they are equipped, and what each one does. Until then, treat companion stats, drop sources, and bonuses shown in previews as preliminary.
