de vosjoli is not a good source. he is a scientist, not a care giver. he has other motives. besides he is a boring person too. alot of his advice is ok but not that. put yourself in your pet's shoes. where would you want to live? in a 5 gal or a 20 gal tank. bigger is always better. I would rather be a frog in my house than yours. and last time I looked redeyes are the same size as a white's.
