Now that sounds like a better fit for a baby. I have my baby in a 10 gal. and it seems to be able to adapt to it every well, was exploring from day one, without any stress from what we could tell at all. Of course it's a little pisser when it comes to being picked up, not biting, but sure puts on a show! I know I wouldn't put her in anything bigger for about another year. Now on the other hand I have my big girl(or boy) in a 55 gal.. and even that at times seems small.........but what do I know??.....lol
