CORY CRUMBLES

Cory Crumbles are a first-of-their-kind scatter food formed into convenient, berry-shaped portions. Crumble one between your fingers over the aquarium to create pieces of different sizes and multiple feeding zones throughout the tank. Instead of crowding around a single wafer, corys, plecos, loaches and all bottome feeders can search, sift, and forage across the bottom - just as they naturally prefer.


Cory Crumbles begin with wild-caught fish meal and contains black soldier fly larvae, krill, egg, and brewer’s yeast to provide a rich variety of animal proteins. Plant matter, including alfalfa, kelp, and spirulina adds nutritional diversity for an omnivorous, whole-ingredient formula.

Every batch is carefully handmade to deliver substantial nutrition without forcing food into the same perfect pellet shape found everywhere else. The varied crumbs allow larger bottom feeders to enjoy substantial pieces while smaller fish search for tiny morsels that settle between plants, rocks, and substrate.

How to Feed

Hold one Cory Crumble over the aquarium and gently break it apart, scattering the pieces across several areas of the tank. Adjust the size and number of crumbs to suit your fish and colony size. Feed only what your fish can consume within a few hours and remove any uneaten food.

One berry creates an entire feeding ground.

PRIME PROTEIN PLECO POPS

Prime Protein Pleco Pops combines wild-caught fish, black soldier fly larvae, krill, and other carefully selected ingredients into a firm sinking wafer designed for plecos, corydoras, loaches, catfish, and other protein-seeking bottom dwellers.

Every batch is handmade in Brooklyn, New York and slowly prepared at low temperatures to help preserve ingredient quality. You'll find ingredients you can actually recognize on the label not mystery fillers hidden behind vague descriptions.

Unlike perfectly uniform factory pellets, Pleco Pops feature a naturally textured surface and two wafer sizes to encourage grazing and accommodate fish with different appetites.

Whether you're feeding growing plecos, active loaches, corydoras, or other omnivorous bottom feeders, Prime Protein Pleco Pops provide a hearty, protein-rich feeding option inspired by the foods these fish naturally seek out.

KELP & WOOD PLECO POPS

Kats Pleco Pops starts with real greens - Alfalfa leads the pack, followed by kelp, moringa, spirulina, natural oak wood, and other carefully selected ingredients inspired by the diets of grazing fish.

HATCHLING FUEL

From day one, your fry need more than powdered flakes — they need real microfoods that mimic nature. Hatchling Fuel is a blend of Arctic copepods, krill roe, and micro-algae sized at 50–200 microns, perfect for fry from hatching through their first 4 weeks of life. Designed by a biologist and produced with trusted U.S. suppliers, this formula delivers serious power for tiny swimmers.
