I have a 2lb bass in my aqaurium at home, he's been in there for about 2 weeks now. He is pretty much trained now, he can eat a nightcrawler right out of my hand. Goldfish dont stand a chance. He will mow thru a dozen in about a day. I tried something new and got a dozen waterdogs last night. Put the biggest one in first, he didnt last 2 seconds. My fish ate 3 more, then just sat there at the bottom of the tank, probably feeling full as heck. Ive learned a lot from watching him feed though! Im going home in a few to feed him another one. Yeah, I think Im a little TOO into this fishing stuff!
