I started with 4 least rasboras in a flex 9. They were fussy eaters but I got them going and they happily explored the tank. Well, I got 4 more and left them in the care of my spouse bc I had a family emergency out of town. I came back to 3 fish...or so I thought! Today, weeks later, I saw all 8 of them hiding in the back of the tank. They're spending most of their time in a cave feature under some driftwood. I want them to feel more comfortable and explore the tank like the first 4 were doing. They are much easier to monitor and feed if they come out. Do you see anything obvious about the tank here? Too bright? Not enough plants?
