Here's the deal, in my ten gallon I had 4 false julii corys (don't get started on shoal size please) then when I upgraded to a 20 long I got 3 more to up their group a little and with more space I thought why not. Long story short the petco guy didn't have a clue (why am I surprised) and stressed them out so much trying to catch them one didn't even make it out of the bag after a 10 minute drive. I have just the corys, about 6 RCS and a bunch of swordtail fry in the tank, all parameters are good but I've seen one single Cory swimming in the middle and top of the tank, only sometimes with the group. And its not like active swimming, just small tail movement, almost just floating. Should I be worried? Is it just stressed out from everything?
