It is a community tank but I only have 1 bala shark, the 2 gouramis and 7 cory cats. Believe it or not my cories spawned and I didn't notice it until I was counting to see how many I had and there was an extra cory. It's my little miracle fish. I don't really have an extra tank right now, or I would put those two in another tank and see what happens. The past couple of days he's been chasing her around the tank. Which is unusual because he normally leaves her alone.
