Hi, is there any chance wild caught Grey tree frogs have aggression/territory issues towards each other? I have had one male Grey in a 5 gal tank for about a year now and wanted to put another new wild caught male in the same tank; is there any concerns in doing this?

The new Grey is in a separate tank now for observation (sickness/health concerns).What is a good time for observation before Introducing a new frog


Thanks.
