There's better protein out there than hot dogs. Some people see a fish eat something once and assumes that it's okay to feed it on a regular basis. Hot dogs don't have the greatest nutritional value and depending on who and where are pumped full of sodium nitrites.
remember, no cook hotdogs.
As a treat, give them raw ones chopped to bite-able sizes
Personally I won't, earthworms, prawn have proteins which are easily digested by fishes
Not a good idea. The grease will cause an oily film to collect on the surface of your water, the high sodium content of the hot dog not good for your fish's health.
Feeding humans hot dogs doesnt have good outcomes either!!! lol Raw hot dogs is not a possibility, they come cooked as far as i know humans can eat cold hot dogs.
