Mosquito Rasbora (Boraras Merah / Phoenix Rasbora) can live peacefully together with neon tetras!
The neon tetras mostly ignore the smaller mosquito rasboras, except maybe during feeding time where they try to snatch the food. There has been zero aggression between the mosquito rasboras and the neon tetras.
Mosquito Rasbora are surprisingly clever and have distinct personalities. One of my mosquito rasbora prefer to hangout near the top of the water together with the neon tetras, while another prefers to swim low near the roots of plants.
