Just got my 4" tig a week and a half ago. I had 200 guppies in the tank before i got him. Been feeding the guppies massivore. Had about 40 left in the tank this morning dropped in some massivore and my tig came out from under his log and eats the piece of massivore. I was shocked. Dropped 3 more pieces in and he woof them all down. That was so much easier then my cichla
