Hold a mirror up to him once in a while and if he seems stressed, then take it away
:nods in agreement: That's what I do with the betta we have. He does his little show-offy thing, flaring his face and fins out, doing this fast-swimming thing. I think he enjoys showing off, lms (laugh myself silly)
Question: How do you know if they're stressed? I wouldn't want to have the betta get stressed and me think it was just having a fun time or something totally opposite of what is actually going on.
