Personal Thoughts & Tips
When I first added an NTT Datnoid, I crammed it into a 100-gallon with crowded decor. It looked unhappy—gliding awkwardly and hiding non-stop. After upgrading to a 180-gallon tank, adding driftwood hides, and refining the feeding routine, it became confident and curious—early perchers perk up when you get it right.
I also switched from only feeder fish to a variety of frozen shrimp and pellets. Clean water and consistency turned it from a lurking shadow into a proud, stripe-showing centerpiece.
