ACNH: Bugs, Fish, and Sea Creatures to Catch Before April

Are you still trying to fill up your Critterpedia? Every month, we have some new bugs, fish, and sea creatures that come and go in Animal Crossing New Horizons. Keeping track of all of them can be information overload, so we wanted to throw together a helpful reminder for you. Here’s a complete list of all the bugs, fish, and sea creatures to catch before April rolls around in ACNH. In other words, catch these critters in March while you still can!

Bugs Leaving in April in ACNH

• Emperor Butterfly

Luckily, there’s only one bug heading out at the end of March: the Emperor Butterfly. You can catch this one between the hours of 5 PM and 8 AM. The blue and black butterfly is not extremely rare, and you’ll find them flying around your island. You won’t get another chance to catch it until June!

Fish Leaving in April in ACNH

• Bitterling
• Yellow Perch
• Stringfish
• Sturgeon
• Sea Butterfly
• Football Fish

You can find Bitterlings all day long between November through March. It’s always swimming in rivers and has a smaller shadow size than average. Next up, the Yellow Perch is one you won’t have another opportunity to catch until October. If you’re still working on filling out that Critterpedia, now’s your chance. It’s available from October to March in Rivers, any time of the day or night.

The Stringfish is also leaving come April, and it is undoubtedly a pain to catch. It’s only available from December to March, so you better take advantage of your chance to find one. You can find it in Clifftop Rivers between the hours of 4 PM and 9 AM. Sturgeons are also leaving in March, and you won’t get another chance at once until September. This one is not too bad to catch, and you can find it in River Mouths at any hour of the day or night.

Another fish heading out at the end of March is the Sea Butterfly, and it’s not coming back until December. You can catch this one in the Sea at any hour of the day, and it’s not too difficult to find. Finally, we have the Football Fish, another Sea Fish that’s only available between 4 PM and 9 AM. This one isn’t coming back until November.

Sea Creatures Leaving in April in ACNH

• Red King Crab

Like the bugs, there’s only a single Sea Creature going away at the end of March: the Red King Crab. You can catch this one during November through March, any time of day. If you miss your chance to snag this one, you’ll be waiting a few months.
