Im planning on getting my daughter a nano tank in the future. What is the best brand? I have heard that lighting is a problem with not being able to sustain corals. Whats the scoupe on the nano cubes? I think she wants around a 12-14 gallon, but not sure. Can you change out the lighting. How does that work with specific hoods with specific brands? She wants to keep colorful hard and soft corals and a few fish.
