Dwarf Chain Loach Ambastaia Sidthimunki 4cm

Overview

The Dwarf Chain Loach is a small, silver-gold botiid patterned with a chain of dark links along the flanks, active by day and often seen hovering in mid-water with its group. It is one of the few loaches that stays genuinely small. Native to the Mae Klong basin of western Thailand, it suits peaceful community tanks with a proper shoal.

Final Notes

Chain loaches are a long-term commitment and are wretched when kept singly, so budget for a group of six to ten from the start. They are keen jumpers, so fit a tight cover, and carry a sharp venomous spine beneath each eye, so net them carefully. Watch for the harmless greying-out display during dominance squabbles. Commercial stock is hormone-bred and home breeding is very rare, but a big shoal is endlessly entertaining.
