Bigeye Squeaker
Synodontis alberti
Also known as: Bigspotted Squeaker
The Synodontis with the longest barbels and biggest eyes in the genus.

About
The Bigeye Squeaker (Synodontis alberti) is one of the more distinctive members of its genus, sporting the longest barbels of any Synodontis alongside a pair of oversized eyes that hint at its nocturnal lifestyle. Native to much of the Congo Basin, spanning the Democratic Republic of the Congo and Cameroon, it's a widespread and adaptable catfish that handles a broader range of water conditions than many of its relatives. That hardiness makes it a reasonable entry point for hobbyists new to Synodontis, though its territorial streak means tank size and setup matter. During the day expect it to stay tucked away in caves or under driftwood; once the lights go down it becomes noticeably more active. Despite being listed as aggressive, it generally coexists well with fish large enough not to be considered a meal. Anything above two inches or so is usually safe. Alestiid tetras, peaceful cichlids like Pelvicachromis, mormyrids, and larger barbs all tend to work. Keeping multiple individuals is possible in a roomy tank, but cramped quarters will bring out the territorial side. Breeding in captivity hasn't been documented, though in the wild the species forms pairs and scatters eggs. A meaty, varied diet suits its omnivorous appetite well.
