Alright, here's a pic of my two tanks:
Ever since I got them, I kept the side of the right one covered, so the bettas don't see each other and get stressed. I took it off today because I thought this would look nicer (and it does), and I was wondering if I could keep it uncovered?
Would this stress my bettas out too much? I know the cups in pet stores are kept right next to each other, but those fish are stressed and unhealthy anyways. Neither one of my bettas are agressive--they don't flare in the mirror or anything. It's been about an hour now and they don't seem to care/notice each other =P
I'm probably worrying for nothing, I just don't want them to be stressed D= Should I re-cover that side or just leave it uncovered?
