Hi, Hop2it ! I am not an expert, but have a few suggestions. First, NO NEW FROG until you find out if current one is healthy. It will NOT be lonely. What , if anything, are you using for substrate in your frogs enclosure ? coconut fiber, " forest substrate, ? I would recommend paper toweling if you can. you can put several layers and keep this moist for humidity. Also easier to check the excrement. Also easier to clean FREQUENTLY to prevent bacteria building up. ALSO, the tree frog will not ingest bits of substrate when it eats which can cause problems. The cricket feeder bowl is a good idea, but you put the crickets into the bowl at night and the idea is they should NOT be able to get out so you can tell if your frog is eating. Another thing I learned the hard way is to be VERY CAREFUL what you use for cleaning both your tank AND your own room in the house. I did a "BIG CLEANING " of my house one day and used a lot of household cleaners that were absorbed through the frogs skin. It was a pacman frog that began opening / closing its mouth and then would go stiff and spasm (seizing). I fixed him by detoxifying him in a bowl of spring water filled just to the nostrils of his nose and changing the water every 2 hours for about 12 hours. Good luck ! I have learned a few things the " hard way "...
