You should get a Nice pair of endlers, I think a few people on here sell them. If you get a trio, you'll have tons in months. Make sure to get the right ratio of 1 Male: 2 Females or the Females will become stressed and die. These are friendly and can go with most fish. Platys, And all variety of Tetras are nice. I really like my Neon Tetras, Black Tetra, Glowlights are nice, Rasboras. I like mini fish, you could do a peaceful German Blue Ram or Apisto if You have the right water.
