I currently have a 5 gallon planted tank with a 3.5 year old female betta Cinnamon. The plant life includes anubias nana petite (2). anubias barteri (1), Bacopa carolinia (2 bunches), Water sprite (2 bunches), 6-8 oz of java moss, some floating salvina, rosette sword (2), Java fern (1), marimo moss ball (3), and some dwarf hairgrass. I have good cover with dragon okho, slate, manzanita branches and dried Indian almond leaves. Would this be sufficent for 3-4 ghost shrimp with by betta, she has poor eye sight and can not hunt, I am more worried about the shrimp being aggresive. I am unsure since I have heard the stories if aggresive ghost shrimp, no not macro shrimp, ghost shrimp.
