just dont buy him an African dwarf frog as a tank mate...he will kill it!
I sadly learned this the hard way, as where I bought my Beta, Blue Bandit, they said the frogs were co habitable...however, I came home from our trip last weekend to find Blue had eaten Ferggies right hand (plus broke her arm) plus had made a sore under her jaw near her mouth!
I very sadly found her dead this morning, floating upside-down (tried to coax her to move several times, even took her out of water to see...nothing)
Very sad...wouldn't have gotten her at all if I knew this was to be her fate...
