Amazon milk frog looking a little skinny?

[Tripe46]

I bought both of my Amazon milk frogs on June 11. They were both about the same size, but now one is significantly larger. I just dumped some crickets in their terrarium and the larger one has been actively hunting since I dumped them in. The frog in question I moved from a high branch to the terrarium floor after picking him/her up to check him out, the crickets are all jumping around in front of him but he shows no interest. Below are pics of both frogs and their terrarium. Any thoughts?


Skinny frog


Skinny frog 2


Fat frog


Two Brazilian sword plants died and were recently removed that provided much more cover higher up, Im planning on revamping the entire terrarium soon.

He does look skinny. Is he eating at all? If he's not, he could already be suffering from some stress-related disease. If he's not eating, I'd get him to a vet for a check-up.

I agree. May be you can put him in an other tank to observe him better? Mine look realy fat all the time!

I think I have found the problem. When I first got them I was putting a ton of crickets in every night as they are Juveniles, and eat a lot. However I noticed that there were still 5 - 10 crickets still hanging around the following day. So I started putting fewer crickets in each night, what I have found is one is a much more aggressive hunter than the other. I watched them for over an hour the other night, and the skinnier of the two showed almost no interest while the fatter one proceeded to eat about 8-10 crickets, he then meandered over to the water and sat. After another 20 minutes or so, the skinner one began to take interest in a lone cricket, so I turned the lights down in the room and dumped in some more crickets, and sure enough he ate about 6, it seems as if he/she likes to eat just not competitively. I'll continue to keep a close eye but the appeared to be about the same belly size before I went to work this morning.

I take my smallest tree frog out of the viv, put him in a critter keeper with a few crickets, and cover it with a towel so that he has some stress free time to eat. Maybe try something like that? If that doesn't work, I'd take him in.
