So, I just got a new thrive tank about a week and a half ago. My baby beardie was of course hesitant about all the new things at first but seemed to warm up to it fairly quickly. But he has been less active the past 3-4 days and isn’t eating as much as normal. My concern is that the screen has those plastic crossbars on top... I use a t5 light but it doesn’t sit totally flat on the screen now. Could that be a problem?? Should I replace the screen or go with a t8 inside???? My only concern with mounting one inside is that my boy is a CLIMBER!!! HELP!!!! ???
