I currently have four GTFs in an 18x18 enclosure and was wondering if it would be possible to mix in a single STF. I have the STF in a seperate tank all to himself, However, the tank is much too small, even for a frog that is less than an inch in size. Would this be a good idea or one that I would soon regret. I just recently seperated all of my whites and green tree frogs into seperate tanks and they lived together for over a year in perfect harmony. Of course the GTF were at maximum adult size and would not likely be eaten by the whites. To my knowledge GTFs are not aggressive eaters and would allow the STF to eat. Any suggestions would be appreciated, Thanks.
