This is a guide for Tap Tap Fish – AbyssRium, with only the Halloween Tank Event information. Updated for 2020! See the main guide for a more comprehensive set of information. Feel free to add any of my guides to your homescreen for easy access, and offline loading of guides you’ve used (on supported devices)!
This is NOT the saltwater tank event. Things are WAY too complicated. Flero. Anyway, for the halloween event taking place in the Abyss tank, see this guide.

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.
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.
