Overview
The bigeye squeaker is an appealing, mostly peaceful catfish for the bottom of a community tank. It takes a little more care than the easiest community fish.
Caring for the bigeye squeaker
Give a bigeye squeaker a tank of at least 21 gal (80 L), with a soft sand bottom, driftwood and shaded caves. Set up moderate flow.
Keep the water at 72 to 79°F (22 to 26°C), with a near neutral pH of 6.5 to 7.5. Feed sinking pellets, frozen foods and vegetable matter over the sand.
The bigeye squeaker is mostly peaceful and suits a medium to large community of robust tank mates. It is fine alone, but it does well in a small group of its own kind. As it matures, it can be a little territorial with other bottom catfish. Breeding is not documented in home aquariums.
Good to know
The bigeye squeaker belongs to the catfish family Mochokidae. It has notably large eyes and a tall dorsal fin. It is also sold as Albert's synodontis or the high-fin synodontis.
In the wild
The bigeye squeaker comes from the tributaries and side streams of the Congo basin rather than the main river. It shelters among wood and roots by day and forages over the bottom at night, in warm, gently flowing water.
