:
They are quiet fish and live well in a community aquarium of 70/80 liters with other Asian fish that have the same needs, intra-specific relationships are less good: males struggle hard and often fight with each other if the Aquarium is not big enough. Recommended fish for coexistence: Brachidanio and Rasbore, Corydoras, Rineloricaria, Botia Sidthimunki. Observe, of course, territorial fish such as cyclists.
The tub must be well planted and have many shelters, shelter and possibly floating plants to avoid fighting that often end with the death of the weaker, and to provide sufficient surface for nest construction. They need a good filtration system or frequent water changes because they bear little nitrites. Remember that in nature they live in stagnant water so little current and movement of water and light not too strong.
