I need some advice from someone soon!! I have an Oscar about 4 inches long and he has eaten 2 feeder fish one right after another and now the 2nd one is still hanging out about 1/3 of the feeder fish's length (so about 1/4 to 5/16 "). Should I grab the the tail of the feeder with a pair of plyers and yank it out or should I just let my oscar do its thing and he will be ok??? Thanks in advance
