Slender Harlequin (Trigonostigma espei)
The Slender Harlequin is very similar in appearance to the Harlequin but has a narrower body and a smaller dark patch. The Slender Harlequin is very peaceful and only grows to 4cm so is best mixed with other peaceful, small fish. Provide some heavily vegetated areas and hiding spots and avoid mixing with boisterous fish. Water quality must be kept high and whilst the fish may adapt to harder water, over the long term they are best kept in neutral to acidic water with a soft to medium hardness. A good tank mate for timid or sensitive fish.
