A reference to the axe shape on their sides. Their common name is Lambchop Rasbora.

Buying Lambchop Rasbora

Pay close attention when buying. The Harlequin Rasbora (Trigonostigma heteromorpha), Glowlight Rasbora (Trigonostigma hengeli) and Trigonostigma espei are often confused. The difference between these fish can be seen in a number of things. Trigonostigma hengeli is the smallest of the three, Trigonostigma heteromorpha the largest. Logically, Trigonostigma espei is therefore in between. Trigonostigma heteromorpha has a pink colour with a large triangular spot. With Trigonostigma espei and Trigonostigma hengeli, it really has a hockey stick shape. Trigonostigma hengeli has a bright orange line above it, Trigonostigma espei is completely orange.

The aquarium

They need plenty of swimming space. Since they swim in the middle layer, border planting is recommended. They also appreciate low foreground planting and it enhances the colour of the fish.

Trigonostigma espei are very peaceful and lively schooling fish that are best kept with 15 or more. They keep well with other fish.

Breeding Trigonostigma espei

The breeding of Trigonostigma espei is quite difficult. Make sure that the parents are well fed with, for example, black mosquito larvae, they contain many vitamins and promote spawning. It is advisable to set up the breeding tank with broad-leaved plants such as an Anubias or an Echinodorus species. The egg deposition takes place on the underside of the leaf, they lay about 80 to 100 eggs. Provide soft water and a temperature of 27 degrees Celsius. The fry can be raised with brine shrimp nauplii.
