Planted-tank friendly

The Bolivian ram's main selling point is straightforward: it does most of what a German blue ram does, but without the same fragility around temperature and water chemistry.

Tank Size

A 20-gallon tank suits a single Bolivian ram or a bonded pair comfortably; this species doesn't strictly require a group the way schooling tetras do, and a single specimen or a true pair are both entirely appropriate stocking choices.

Water Parameters

72-82°F and pH 6.0-7.5 cover this species well, genuinely wider than the German blue ram's narrower, warmer preference. Ammonia and nitrite must still read zero at all times regardless of this species' greater general tolerance.

Substrate and Foraging Behavior

Provide soft sand or fine gravel to support this species' natural substrate-sifting foraging behavior; a coarse or sharp substrate can cause barbel or mouth irritation over time as the fish repeatedly sifts through it searching for food particles.

Recognizing Pair-Bonding Behavior

A bonded pair will often claim a flat stone, broad leaf, or a cleared patch of substrate as a potential spawning site, defending it against other tankmates. This is normal reproductive behavior rather than a sign of general aggression, and understanding it helps distinguish a healthy pair defending territory from a genuinely aggressive individual.

Diet

An omnivore accepting sinking pellets, flake, and frozen foods like bloodworms or daphnia; sinking foods suit this bottom-dwelling species better than foods designed for surface or mid-water feeders.
