I got a BTA a month ago. It’s been doing pretty well and I’ve fed it a couple times since then. However, it’s been doing this since i got it. Where it will deflate fully and look like it’s dying but be fine an hour later. The only thing i can think of is that the lighting might be too bright as the store i got it from had it under dim lighting. Thing is, I acclimated the lighting for 2 weeks. Going from 30% up to 100% on my Kessil a360we.
