You can purchase a Blimpfish from the one merchant in Hydropolis

Pontus prides himself on being the finest marine biologist in all of Hydropolis, and he wants to test Evan’s knowledge of life beneath the waves. The first item he wants you to find is a poisonous fish, and that’s the only clue you get. What you need is something called a Blimpfish and despite being a four-star rarity, you can actually purchase it from the food vendor in Nautes Harbor. Bring it back to Pontus and the second item will be a piece of poisonous coral. This is Pincushion Coral and you can find it on both Makronos and inside of the Abyss, so you probably have some already. The final item will be a piece of seaweed that is so silky, one might use it as a scarf. This one is Seasilk and while you might be able to find it in/around water, you can easily obtain it via the Fresh Fish Market in Evermore (level 2). Handing this in will bring an end to this quest.
