Thanks to all that replied to help me out.
Yes, they are in a community tank.
I think they get a good mixed diet of flakes, tetra color is one of them, live and frozen brine shrimp, and what drives them totally insain, fruitflies. The Bleeding Hearts jump right out of the water for them.
Since my Bleeding Hearts are well mannered and it sounds the Serpaes are a bit over active, I'll get 2 more Bleeding Hearts. Hopefully with 4 in the tank they will be in there "show off" dress most of the time.
Thanks again.
