Unfortunately Lynn I haven't been able to locate any others at present. I do believe I know which one may be the mother though. One of the larger frogs has been staying hidden in a tight cave under a log in the back and has been very seldom seen the past month or so. I call her Moca as her bronze/brown coloration is fairly light in comparison to the others. She used to hang out in the front but now when I do the feeding time she just hops out, grabs food and hops right back in. The single froglet is also hanging around outside the log cave so I suspect a connection.
