Overview
The Tanganyika striped spiny eel is a solitary bottom dweller for a rocky, hard-water tank. It is moderately demanding to keep.
Did you know
The Tanganyika striped spiny eel's scientific name, plagiostomus, means slant-mouthed. It describes the obliquely set jaws of this eel. That mouth shape is well suited to picking small food from the crevices and surfaces of a rocky lake floor.
Caring for the Tanganyika striped spiny eel
Keep the Tanganyika striped spiny eel in a tank of 79 gal (300 L) or larger, with a secure lid. Give it a sand base for burrowing and generous, piled rockwork with narrow gaps to explore. It keeps to the bottom and comes out to forage in quieter hours.
Match the lake's hard, alkaline chemistry, at 75 to 81°F (24 to 27°C) and a pH of 7.8 to 9.0. Keep the water clean, stable and well oxygenated, since it is adapted to a large, chemically steady lake. Feed meaty foods such as chopped earthworm, prawn and frozen bloodworm, with the odd piece of mussel.
Keep it singly, as it is territorial with its own kind. It mixes well with larger, hard-water tank mates and is peaceful toward fish too big to swallow. It will eat small fish, so choose medium-sized, even-tempered companions. No aquarium breeding has been recorded.
