I'm sorry Dr. Jesse Phd in everything fish related, I forgot that no matter what ALL feeders have disease and no matter what ALL fish will become aggressive when they eat them. For your information if you get feeder fish from a reliable source they have NO disease and NOT ALL fish will become aggressive if you feed them live. I have been feeding all my fish live for years and have never had a single aggression issue or issue with disease. Why don't you think about about all the possibilities before you attack someone about there suggestion. How long have you been in the hobby? exactly! I have been in the hobby longer than you have been alive my friend!! Why don't you focus on getting a job and paying off that huge water bill you are crying about!!! I'm truly sorry for derailing this thread but this guy seems to follow me around and bash everything I say so I'm just sticking up for myself against a little high school punk.
Not to pick on you or anything, but I just got three 5" - 6.5" Retropennis Bichirs and have them in a 40G growout with three Fl. Gar also 5" - 6" range. I had small Goldies in for the Gar to consume, and the largest of the three Bichirs also hit one of the feeder goldies. It died within a few days, as it looked preganent from swallowing the goldfish and NOT being able to pass the skull. I have NEVER had anything remotely like this from my Gars. They either can not swallow their prey, or if they somehow can swallow the prey, their insides are strong enough to either crush the bones of the feeder to pass through the digestive track or at least digest it quickly enough to pass the digestive track before death.
I quaranteen the "F" out of my feeders and nothing even remotely like paracitic infection.
