You are so right! These tanks are expensive. They sure are pretty though. This is what I just ordered for my 11 froglets. I think it will be big enough for 11 of them (because they are one of the smaller type tree frogs), but I won't know until next year when they are full grown. I hope I don't have to buy an additional one. I can't really say how many it will fit comfortably. I think I read somewhere about a ratio of frog to gallons, but it is escaping me right now. Maybe someone who has had Gray's for a long time can answer. If you can't get all the money together by Christmas, charge the rest! Then you can have it delivered and say "Oh, look what Santa sent me".
