Is he too thin?

[Cuillan]

Sorry photos don't seem to work on a phone, I feed him medium crickets dusted with calcium and multivitamins obviously they are also gut loaded, he did have impaction a couple of weeks ago because he was on moss, I've just changed his tank because the last one was always to moist.

at this point we can't say much or help much either without pic of the frog.
if he is not impacted anymore and eating, but looks thin, all you can do now is to feed him - small size, but good food ( chunks of nightcrawler, dubia ) and more often using 15 min rule- give as many as it can eat in 15 min every day, you can do some wax worms, they have high fat content, but for skinny frog are ok, you can give him hornworms ( smaller ones) as well.
you can also answer to trouble in the enclosure questions and post them here for us to review and advice on any changes if needed.
