Tap Tap Fish – AbyssRium Space Event All Hidden Fish Guide

abyssrium space event guide

This is a guide for Tap Tap Fish – AbyssRium, with only the 2019 Space Event formation. See the main guide for a more comprehensive set of information and for links to other events. Fun Space Event fact: this event was ‘teased’ in a glitch in the game two years ago!

New Ownership

Not directly related to the update, but AbyssRium has come under new ownership. Flero Games purchased it from Cheetah Mobile. Don’t panic too much, because Cheetah Mobile already acquired the game from it’s original developer 2 years ago, so all of the usual bad “soulless corporate acquisition” stuff has already happened.


Flero games seems to at least care more than Cheetah Mobile ever did, adding a GDPR notice to the beginning of the game and they’re apparently actually answering Facebook support messages again, which Cheetah had been ignoring for the better part of a year.

Space Event Gameplay

General Event Info

Events slowly rollout from the app stores (every time, yes it sucks), so don’t panic if you don’t get it. APKs have been disabled, but you can use the Tap App (not affiliated with me!) to download the update early on android. You can delete the Tap App afterwards. There’s no way to get it early on iOS.

See here for how to use Nox Player to automatically collect event currency on a PC/Mac so you don’t have to destroy your fingers.

The event is in the Abyss/Saltwater Tank like most events, and it will expire once the event time is over, but your event currency should roll over to the next event (unless it doesn’t, because the devs like to do that).

Hermit Crab Levels

The Hermit Crab is the key to completing events. Buy the Event Dye to unlock it, then upgrade it as soon as possible. The costs and earning rates of each level is listed below, but every upgrade pays for itself after a day or so, so don’t worry too much.

New Hiding Fish (October 14th)

Starting October 14th, there are new hiding fish in the Saltwater tank. They’re not exactly related to the Space event, but I’ll list them here for simplicity. They are likely to expire around the same time as the space event.

Despite the name, Hiding Fish are not “Hidden Fish” and it’s a simple Gachapon/lottery system. On average it usually takes users over 100 “pulls” to acquire one of each fish and unlock the final fish. Costs increase each purchase, making this a very expensive affair.

No Hiding Fish are required for any unlocks outside of the final Hiding fish that requires one of each.
