they do look good and their is great as well. Also if you ever want to feed live food for any reason stay away from goldfish and go with guppies but you do need to quarantine both anyways to make sure there are no parasites or disease. But you can also feed them earthworms,and wax worms. But wax worms don't feed to often because some have found their animals to become addicted almost. The earthworms though can be great as long as the frogs like them. For example my male would strike in the beginning but now he just goes to the other side of the tank. But my female as soon as one hit the water she is there. I do this every so often because i have an axolotl that eats them to so i use it as a treat but really as long as they accept them you could even use earthworms or trout worms as staple diets. But i don't because i personally rinse the dirt off and its some what time consuming for me.
