Pseudomugil luminatus, the Red Neon Blue Eye.   These fish were bred in my home about 9 months ago and are now full grown young adults ready to breed.   This auction is for five adult males for your display tank.  A great fish for a planted tank. Peaceful.  This group of fish are kept in hard suburban tap water.  The photo is a scoop of random adult fish from my grow out tank.   They appreciate a planted tank and live food, at least occasionally.
