There is a calming feeling to watching tropical fish for beginners. I like the ones with bright colors. The fish that seem to glide through the water with their beautiful colors magnified in the water of the tank and the glass that holds it all in. I recently saw a bicolor angelfish, bright blue and yellow. The colors were so vivid that they appeared to be neon. There is also a flame angelfish, which is fire red with a blue tail. The list goes on and I don't have time to talk about them all. I just want to say that the splendor of tropical fish is amazing and wonderful to see.
