Hello all! I've had my fish for a couple of days now, & I'm already incredibly fascinated by them! I was wondering if anyone can tell the gender of my rainbow shark & blue dwarf gourami? Also, I feed my gourami as much as he can eat in a couple of minutes, but it seems like he's still hungry and asking for more at the glass when he sees I'm around, is this normal? He tries to eat everything, including my finger! Lol Thanks in advance!
