So I am looking at setting up a 4g Pico tank. I had a 30g in the past but had to move and sell it all and I need back into the hobby. I am looking at getting the Cadlights 4G Mini Series. Seems to be excellent quality with a light that can support corals well. Anyone have any experience with this company? Also what would be a good CUC for such a small tank? I was thinking 5 astreas, 4 nassarius, a peppermint shrimp, and maybe 1-3 crabs. Let me know what ya think and any tips you might have.
