The brown frog is a spring peeper. Tell tale marks are the "X" on it's back. Not trying to escape at all. That's what they look like when they anchor themselves to the glass or a branch. They'll stay like that all day. They tuck themselves in a corner or crease.
Yes, the other frog does indeed look like one of the two grey treefrog species (H. Versicolour or H. Chrysoscelis). Grey treefrogs have one of the higest abilities for colour changes amongst tree frogs, so it is not surprising to find a green one.
ahh very true and also it allows any parasites that may not normally be transferred between species transfer quite rapidly to quickly cause a major problem.
although it does look very nice when species are mixed. and it often looks A LOT nicer when you do and if they have a natural setup.
Then again, lions and gazelle are found in the the same habitat, but you wouldn't mix them in captivity (extreme example I know, but you could easily get at least get injuries from mixing frog species)
The frog looks to be an Eastern Gray Treefrog (Hyla versicolor). There's a chance that it's a Cope's Gray treefrog (hyla chrysoscelis), but it appears to have a white spot under its eyes, which is a give-away.
Another thing that can be used is that Cope's will lose their mottling on their back after the breeding season, or when it's warm, and will typically be a solid lime green. But the best indication is the white spot, or the breeding call.
yeah as i was saying earlier dna testing is really the only 100% to be sure what type it is.
and using the call is a good way but you have only got one of the gray treefrogs so it may be very hard to test it with others though i suppose you could download a call of the internet
I have 2 common grey tree frogs in a separate tank and this particular green frog here hasn't grown OR changed color at all, like my common greys do, the entire year I've had it. I don't think it's a common grey tree frog. I'll have to get some better pictures and maybe someone would be able to identify it by that. The one I provided is blurry. I haven't heard any calls from it either. My commons keep me up nights at times!
By the way, this green one was found in the same area I found the spring peepers. I understand it's debatable on mixing species but I also think it's not really harming much (minus the parasite issue, that I agree with) with this particular arrangement. I would never put small frogs in with large ones. That's why I was keeping this small green one with the peepers and the tank I have them in is pretty large. Once I can convince my husband to build me my own critter room/greenhouse, I'll get a separate tank for it.
My axie is acting woerd he was a rescue as stated in a different post he got better and now seems to be deteriorating again...again all tank conditions are OK and as should be. He seems to have some black dapple like pattern under his bottom lip? Is that normal? And his two back feet have a little wierd growth? Almost? Tiny tiny tiny lump. His capillaries in his feathers also appear darker and more visible. Any help would be appreciated
