I just got this new rainbow bta earlier today. He walked into this spot right away under a rock where he gets little to no light. I doubt it's good for him and I want to see him. What do I do? Will he walk around more? He has settled there for about 3 hours now.
BTAs are funny like that when in a new environment. Mine did that too and started to move and found a sweet spot where it gets enough light and I can see it easily. Give it a few days! Also, they don’t love high flow especially at first.
