Two 8-week-old Dwarf Gourami fry. Siblings who were spawned at the same time. One is twice bigger than the other. The bigger one first started to show sign of color during the 7th week, and he is already 70~80% colored up. The smaller one is a female(I thought she is a male). It might look like the bigger one is bullying the smaller one at the moment, the smaller one is always up to no good either. I've caught her attacking her brother 5~6 times in a row on at least two occasions, although her brother dodged every hit. Note: I had separated them into two tanks shortly after. They are both the bosses of their own tank.
