I have a male veil tail. I think he is more on the aggressive side. He flares at my nail polished finger and will attack anything I dip in the tank. He jumps at me when feeding. When I first got snails, he nipped at their antennae for a few days but then left them alone. I'm wondering if there are any other fish I can house with him so he's not so bored. He's in a 10 gallon tank.
