This evening my new BP (had him for two weeks) was climbing around in his tank after I tried feeding him (he didn’t eat but that’s a whole other thread). As he was stretching out to reach top of tank I noticed he had a tiny whistle or at least I think it was coming from him. It wasn’t very frequent and o my heard it a few times. Then it stopped and I stood watching as he climbed around for 5 minutes and didn’t hear anything. any thoughts? Could it be RI? Don’t want to go through the stress of taking him to the vet if not necessary as I’ve been working hard on getting him de stressed enough to feel comfortable to eat.

thanks!
