One last thing about the Massivore...
About how much should I give my senegal per feeding (again, he's between 9-10" long)?
Also, if he is the only fish eating the stuff, should I opt for the 2.61 oz bag or the 13.4 oz bag? I'm kind of on a budget with the holidays coming up and don't want to have to order food again for at least a month or two.
