2019-11-05: A patch added Halloween-themed Expand items to the Main tank, along with the Greek Event. If you don’t have the greek event update yet you won’t see it.

2019-10-18: A patch was released that fixed a vitality curve issue in the halloween event to make the event easier, and reduced the 2019 Jellyfish and Seahorse requirements. The guide has been updated to reflect this.


2019-10-15: All new halloween event hidden fish found! They’re in a pretty nice table, I might fancy up the older hidden fish into tables later on. Video Guide added.

2019-10-14: Get s p o o k e d the update is releasing on slow rollout! See the new fish here. There’s also a new set of “hiding fish” in the space event.

BTW, for those having trouble with Facebook cloud saves or trying to transfer saves between Android and iOS (either way), check this reddit post out.

It is a slow rollout and will take you a while to get. Despite literally every single update AbyssRium has ever done rolling out in the same (stupid) fashion I still get spammed every time it updates about this. Please don’t ask about it.

New Event Style

As many suspected, the Freshwater separate coralite situation was used as an excuse to make Candy worthless. The new event is in a totally new style similar to the Freshwater coralite. I’ll explain the tabs and their functions here.

Your candy from prior events carries over, but is basically totally worthless. There is no per-tap vitality so don’t waste your time tapping beyond collecting candy. The basic loop is collect candy, use candy to upgrade the Witch’s Pot to get more Vitality, use Vitality to buy event fish, event fish increase the candy you get allowing you to ultimately get more Vitality and so on.


Complete the tasks to unlock “coral”, cosmetic vitality producing items (that do not produce enough vitality to be worth it, but they unlock fish so get them anyway). The Quest requirements are in a section below.


Candy is now only used to upgrade the Hermit Crab, which now functions like the Coralite. Upgrading the crab with candy will produce more “Halloween Vitality” which is spent on Halloween fish.

Collect 50 candy from bubbles to make the hermit crab dance, like before and it still earns candies in return; a lot more now, so prior stocked up candy is basically crap. It now sleeps for an hour after dancing, and can be reset by watching an ad.

There are additions to the crab that can be unlocked via the Quest and also upgraded in the same tab as the Crab. They’re basically Coral.


All fish are in the same tab, and only in the Halloween Coralite. They cost Halloween Vitality instead of Candy, and prior event fish are mixed into the same huge list (and prior purchased old event fish do not count!). See below sections for prior event hidden fish unlocks.

Fish are separated by tank meaning your old Halloween fish cannot be put in the Halloween Tank, and new fish bought in the Halloween Tank cannot be put in your saltwater or freshwater tanks.

Fish prices rise exponentially with each purchase, so don’t buy too many repeats that are unnecessary, focus on unlocking all fish first, then decide what you want duplicates of.


This is where you upgrade Trick or Treat (the Crab dance skill), and also where two extremely overpriced consumable boosters are. Don’t bother buying the ones with pearls.

Just upgrade Trick or Treat to level 10 as soon as possible, it will be required to complete the event, and you’ll get the gems back from achievements/quests in the event anyway.

Idle Vitality Is King

After 2 years of idle vitality not mattering at all, it’s actually best to let the full 3 hours of idle vitality accumulate in this tank. Unlike past tanks, it actually matters a lot, and Candy drops from tapping bubbles is increased drastically for the first ~20 seconds after claiming the idle vitality.

You can get several Coral levels from tapping the boosted bubbles so check every 3 hours and don’t play too much “actively” because idle is so much more effective.

Halloween Event (2019) Event Stats

Start Date: 2019-10-16
End Date: 2018-11-16*
*End dates are roughly estimated; events last around a month. Event Tanks don’t entirely close, however, you’ll just need to watch an ad (30 minutes access) or pay pearls (1-7 days access) to enter. No progress will be lost at the ‘end’ of the event.

New Fish: 15
Total Fish: 73
IAP Fish: 3 IAP fish total, 1 new.
Total Cost: Not an easy nor particularly relevant metric for Tank events. Costs and income rise infinitely, there is no longer a cap on production.

General Event Info

Events slowly rollout (every time, yes it sucks), so don’t panic if you don’t get it. Expect it by the end of the week after it first starts rolling out.

We never know when the events end until less than a week before they do, they’re usually at least 4 weeks long though.

Currency from prior events will be preserved (but invisible) for later events, so feel free to save up.

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.

Hidden Fish

Note that some lock conditions for non-hidden-fish are listed on the lock icon rather than with the other lock conditions, you need to meet all conditions and no popup will tell you when you unlock them since they are not hidden. Most fish have three unlock conditions this time and will not unlock before all three are met.

I’ve split the fish unlocks out per year, since there’s too many to list in one go and many players may have them unlocked from prior years’ events anyway.

Regarding Tombstone unlocks, just take 5 pictures of all 4 Tombstones and it should count, then just ignore the tombstone unlocks unless you’re sure it’s what you’re missing.

Halloween 2017 Normal Fish
  • Mummy Mahi Mahi
    • Own 33 event fish!
      • Most people that can’t unlock it overlook this requirement, it’s listed under the lock on the right side of the fish list because the devs don’t know how to design UI
      • Note that for non-hidden fish, nothing pops up saying you’ve unlocked it
    • Take a picture of the #1 Tombstone
      • They’re NOT numbered, but this is one of the two in the front
      • You will not get a pop up confirming it worked, since this is NOT a hidden fish.
  • Devil Boxfish
    • If you don’t get this one, you probably forgot to tap on the Witch’s Pot to focus the camera on it. All camera unlocks require focusing on the target.

The rest of the 2017 and 2016 Halloween Fish are listed ingame and not hidden, I just listed this because everyone is tripped up by the 33 event fish unlock. Most fish have a requirement under the lock icon too

Halloween Event Quests

These quests give rewards (including Candy, Vitality, and Gems) and unlock the next “coral” in the game. They’re required for fish unlocks and help you progress in the event, so keep an eye on them.

Everything in this event only counts what’s in the event tank, and only gems transfer between tanks. Thanks to /u/farmerlesbian for writing these all out because it was way too boring for me to do.
