I have think at this point, anything before they got here is pure speculation…
They have soft sand, neutral Ph soft and water… they have been shoveling mouthfuls of sand… the target do come and goes, right now, they are all just barred… there is some red on the tail, light shading
Funny thing about the spot… it only shows up in pictures… looking at them right now, no spots, then took this picture trying to show the color on the tail, and the spot shows up on the picture??
