I currently have a 10 gal tank with 6 neon tetras, 4 black phantoms. I would like to add 4 more tetras of small size to this tank to finish it off. Some suggestions to me were: Lemon tetras, glowlite tetras.
Anyone have a suggestion on what I can add to finish this off with nice color?
Also, I need to get a cleaner and would like to get an otto cat. Plecos just get to big, been there many times. Will one keep this tank clean or would two be better?
