My Betta Enisae

Have 5 of these from exchange program. These are F1 bred locally. Turns out to have 4 males and 1 female. The setup is without substrate, just plain tank with bogwood and Java fern. The 5 Enisae are now adult form. Spawning took place one but no success. Female shy away hiding among the heavy planted setup. Typical of this species is the male with a black, turquoise and white band on the anal fin.
