WoW. I am watching something I have never experienced so far in the many years I have been in the aquarium hobby. Recently I installed moonlights and to my surprise each of my fish are acting more and more naturally. I have attached me tomato clown fish start digging holes into the substrate just before or at the time the moonlights come on. I have also noticed that my puffer fish now sleeps on top of one the fake plants I have in the tank. Before the moonlights He hid inside a big boat I have in the tank. I notice that there eating habits have changed and they tend to be a lot more selective in the foods they eat. This is turning out to be a problem though heheheh. My puffer used to eat anything I put into the tank. however he is started to like marine granules and Live brine shrimp. He doesn't seem to like anything else I put into the tank. My tomato clown is now more finicky as well. Its great to see my fish acting more naturally.I'm very glad I set up the moonlights. I hope you all have fun with your fish. Please let me know your experiences good or bad with your aquariums.
