Aquarium Features

Signature 45° mitered edges and low-iron, high-clarity glass provides an enjoyable viewing experience and enables closer edge-to-edge cleaning with the preferred glass cleaning tool/algae scraper.

Black silicone discreetly hides the appearance of coraline. This line of aquarium utilizes thicker glass to prevent the need for euro bracing at the top.

Tanks feature a sleek white bottom, allowing for a bare-bottom setup without exposing equipment in the sump.

Otocinclus Catfish

The otocinclus is a species of catfish that lives in freshwater and makes a great pet. These fish are known for their algae-eating behavior, and are peaceful in nature. Aptly named, algae eaters are often placed in large aquariums to help keep algae from overgrowing. These bottom-swimming fish feed on green algae and vegetable matter, moving along the surfaces of your aquarium scraping green algae with their sucker mouths. They also eat all kinds of commercial flake and pellet foods, but must get sufficient algae and vegetable matter, such as fresh zucchini, romaine lettuce, spinach or spirulina pellets.

Ghost Wood

Ghost Wood delivers a dramatic glow‑up the moment it hits water. Dry, it’s pale and weathered; submerged, it darkens to a rich mahogany that glows under quality LED lighting. Its smooth, sandblasted trunks and sweeping branches give a clean, sculptural look without the tangle of softer woods, making it ideal for defined, mature layouts. This wood is the one that really comes alive! Talk about a spooktacular glow‑up.
