i added another branch tonight. i just have to make the tank escape proof, and then i think it's will be the boys' new home. then i can started getting them friends. hmmmm....wonder how many white's i can put in a 125 gallon tank....lol actually i am thinking 6. as far as them drowning? i'm not really worried for a few reasons. 1) is i fully trust 40 million or so years of evolution. 2) is that i have plenty of places for them to climb out of the water and 3) between my kids and i, my tanks are monitored darn near 24 hours in a day. the other thing is, i have a pretty good suspicion that it would take a mighty long time to drown a frog. kinda like drowning a dolphin. can it be done? yes, but it ain't easy
