Just put 4 Tuna blue over my arowana tank. All I can say is wow. The Leichardti under it makes it the best looking fish I’ve seen I think. It’s absolutely beautiful. Iradecent colors, pinks, shiny just shocked the lights make such a difference. My fish is about 20”. Even my Datnoids and African look amazing. Highly recommended lights. Anyone else have any fish that look wild under kessil I want to add more.
