My daughter talked me into this little frog last night at the pet store. Tonight he is floating around the top of the tank and can't seem to stay at the bottom. He is in a community 15gal tank with a couple neons and guppies.
He got stuck to the filter earlier and thinking he had died I went to get him out and he darted off the the bottom for a couple minutes and floated back up.
I really don't know what to do.
If he does die she will for sure want another. Can anyone tell me how to tell a healthy ADF from a unhealthy one?
