All of the above are fine. Rinse that pool filter sand. Mine start moving around a good bit once the water hits 60 and then it’s pretty much non stop action- though you have to sort of pay attention and get some polarized glasses since they aren’t 13” long and orange and white. But they’re cool little cichlids that stay busy and look really cool. The handful of fry that you bring in to see in the fall will really bring a smile.
