Alternative name Melanorivulus bororo.

Rivulus bororo was described in the same work with Rivulus paresi by the Brasilian scientist W.J.E.R. Costa at the end of the year 2007. Both species originate from the upper Paraguay river basin. Rivulus bororo was discovered in the Santana River drainage.

It is distinguished from the remaining congeners endemic to the Paraguay basin in having close red dots on flank, arranged in chevron-like series with the vertex on the mid-lateral line and red bars on caudal fin in males. Rivulus bororo is distinguished from all other species of Rivulus in having fewer mandibular neuromasts. It has similarities with R. violaceus from the upper Mortes River basin.

No detailes yet but is believed not to be different from other species within the Melanorivulus subgenus. So, keeping and breeding is easy but a good cover of the aquarium is necessary because there ability to jump, even true the smallest opening, is unbelievable.

This species can, if there is enough space for them, housed in a tank with more males than one only and several females. If separated before and brought together again however, they can be very agressive to each other and fight to become dominant to others. The best way to have much offspring is to put a pair or an trio in a small tank from 10 liters with a small filter in it or with some airation.

On the bottom some peat moss or dark gravel and a floating "mop" to give space for laying there eggs. The fish will, if they become a rich varity of life food, spawn during there whole adult life and produce daily between 5 to 15 eggs. The eggs should be collected by hand and stored for about 14 days in a small container. Eggs are 1.6 mm and amber colored. It is wise, to add to the water you store the eggs in, some acryflavine to provent fungus coming up. After hatching the young fry can eat fresh artemia nauplii without any problem. It takes probably 4 to 5 months to raise them to maturity.
