Giant. Congrats!!! See the dorsal ridges? Also notice the neon green color of the dorsal stripe. It's two other stripes to the sides of the dorsal are pretty subdued which is atypical of most adspersus juviniles. They may show up more as it grows. It's gonna grow fast if you keep him fed and supplemented.
Get him off that moss. use only coco fiber (eco earth is what I use). He can ingest it (they are crazy little predators) while feeding and become impacted.
You are going to enjoy the hell outta him/her. Feed it LOTS. Stick with a good staple of nightcrawlers and roaches/crickets. Stay away from high fat. Dust with 'high quality' calcium with vit. D3 (don't use heavy duty UVB...2.0 at the highest; they don't need any UVB. Just provide calcium with D3) evry third feeding. Vitamin supplement once a week. No need to feed mice (one every month at the most....I do one every other month), they are super high in fat and the vit A from the organs is terrible for these frogs in high amounts.
I would recommend Miner-All brand calcium (it is the best out there and reasonably priced) from stickytongue farms (google it). Also Vit-All vitamin supplement (also from STF).
In six months it will look like one or the other of the beasts in my avatar to the left (male is in back)
