🐟 Spanner Barb (Barbodes lateristriga)
Large Active Barb • Distinctive T-Bar Marking • A Strong, Flow-Loving Stream Barb
 
📋 The Spanner Barb, also called the T-Barb, is instantly recognisable by its dark T-shaped or spanner-shaped marking. It's native to clear, highly oxygenated forest streams across the Malay Peninsula, Sumatra, Java, and Borneo, often found near waterfalls in the wild, and it has a silver-gold body with bold dark vertical bars and the signature T-shaped lateral marking.
Strong water flow and high oxygenation bring out its best, given its waterfall habitat. It reaches up to 18cm, so adults suit a large, long tank of at least 500-600L, and it's sensitive to poor water quality, so frequent partial water changes keep it thriving. It appreciates plenty of vegetable matter in its diet. Juveniles shoal readily, but as they mature, adults tend to become more solitary, so expect looser grouping over time rather than a permanent tight school. It will eat live plants and small tankmates, and some individuals can be nippy, so choose robust plants and tankmates with this in mind.
