Went to my LFS today and when I walked in noticed a new betta display. It has a built in timer to do 12 hours on and 12 off. All the bettas were active and showing off their beautiful colors.
Just thought I'd share it with you.
Before actinic lights came on the market, we used to get Flashlight fish and Pinecone Fish into the store so we set up a tank with some of the original black lights from the 60s so that people could see their eye lanterns when the lights went out. We kept that tank in a darker section of the store so that it was easier to see them without endangering the customers with dim lighting. People told us it was a cool idea
