Shrimp will love the lava rock and so will any babies. I scrub mine with just water and vinegar and then pour boiling water over them 2-3 times. Or they can sit in boiling water but DO NOT BOIL THE ROCKS THEMSELVES. They could explode. Hornwort is also great.
That’s a personal preference really, how much decor you want. Your shrimp won’t really care. I’d do at least two myself. Just play around with it once you add plants and stuff. You’ll find what looks best to you.Any idea how many rocks I should put in? they are about 3 inches long
Second inhabitants: what ever these white things are.
Also what do you think of my scape?
Do you even need a heater? Neos are pretty tolerant and can tolerate cooler temps.
