The spawning occurs for a few hours or so, within 15-20 cm of depth. It requires a very soft acidic and higher temperature water that ranges from 73 to 82 F (23 to 28 C). This makes aquarium breeding quite hard but still can be successful if done right.

Put in a variety of leafed plants where they can deposit their eggs. Dim lights every now and then to provoke the fish to breed . After spawning, remove the adult fish from the aquarium to protect the eggs and the fry

The female fish may lay a few hundred eggs at once, mostly attaching on plants or dropping on the gravel floor areas of the aquarium. It is important to remove the adult fish after spawning because cannibalism is apparent among egg-scattering species.

Since this species lives in freshwater, you can easily substitute tap water with de-chlorinator, a certain chemical that removes chlorine from the water.

Lambchop rasbora (Trigonostigma espei) are active fish species that are often swimming and playing in school inside an aquarium tank. However, they tend to be shy and would hide in plants if housed with bigger tank mates.

Instead, you may house them with non-predatory species like cardinal tetras, bettas, neon tetras, small barbs, dwarf gouramis, danios, other small rasboras, and cory catfish. Nevertheless, as long as you have a well-planted tank, perfect temperature, and good water quality, then you can keep these peaceful fish at ease.
