Hi there
frogs in general are completely fine alone. If you do plan to give winston another tankmate, i would get a larger tank. You can tell the sex in WLTFs by looking at their throats and if it is dark and baggy and croaks, its probably a male. I would think yours is a female because of the silence that is heard. i would preferably get another WLTF about the same size, because these frogs are verocious eaters and will eat anything that moves
Good luck with your frog!
