(female/male hatchlings)nlike other hatchlings, the tropical cerapicta prefer to build things rather than play. Be it a castle made of sand and colorful pebbles or a hideout of algae, these hatchlings put their creativity to good use, always finding new things to add to their small constructions. When not busy collecting rubble for their architectural plans, the hatchlings chase starfish alongside their parents, mastering their innate hunting skills. They are fierce even as hatchlings, never backing down from attacking something bigger than them if feeling threatened. Water magic comes naturally for them and the young cerapicta will sometimes use it in small flows to ruin their recently built castles if not satisfied with the result, or, in other cases, to playfully scare nearby creatures.

Also there is a typo in the description right at the beginning, the 'u' in Unlike is missing.
MISSING CREATURE FOUND! Probably found in the Koi Pond
Common Cerapicta (no egg sprite atm, may be the same as the Tropical)
(female/male)Common cerapicta hatchlings are carefree and playful, always up to building something. Be it a castle made out of sand decorated with colorful pebbles, or intricate hideouts made out of algae, these hatchlings always put their creativity to good use. They can easily get lost while collecting rubble for their small structures and often spend a lot of time gathering more and more things on their way to their homes. Because of this, they are not too skilled at hunting for their own meals. The hatchlings are very dependable on the adults and expect to be fed by them regularly. Water magic comes naturally for them, and the young cerapicta will sometimes use it to demolish recently built sandcastles if they are not pleased with the result.
Known for their vividly colored bodies, common cerapicta are small, zealous creatures found in freshwater ponds. Adapted to the pond climate and the lack of starfish, the common cerapicta feed exclusively on parasites. Along with keeping the other pond residents free of parasites, the common cerapicta also take it upon themselves to keep the area clean of any rubble. Using water magic, they push and pull things around to their liking, and on some occasions, they even move other creatures. Whilst small in size, the cerapicta are brave creatures. Barely reaching five centimeters in height, they will take on creatures that are up to six times bigger than them, knowing they can count on their potent water manipulation abilities. Magis who travel wide masses of water consider them useful companions. If given enough treats, a group of common cerapicta can be trained to push and even power small vessels.
I was so sure it'd be a hybrid with Krill or Royal Squilla!
