A strange thing happened to my gulper about two weeks ago. Whatever I feed him I always stuff a few Hikari Bio-Gold pellets in so he gets his nutrients. I have fed him shrimp, tilapia, flounder ect. Well two weeks ago they had a sale on muscles (fresh still in the shell). I fed him one with about 6 med sized Hik Bio-G pellets stuffed inside. He ate it like always and went back to his drift wood where he likes to hide. He was fine when the lights went out around 9:30pm. The next morning he was no longer black but gold. Yes I mean gold, it didn't even look like the same fish. In fact my wife was ready to fly off the handle cuz she thought I bought "another expensive fish". After I explainded it was the same fish I started to notice he was breathing very heavily, almost gasping for air. He stayed that color for about 48 hours then back to normall. The color was awesome but the way he was breathing was not. I through the muscles out, and decided never to feed them again. Could he be allergic to muscles?(yeah I know how stupid that sounds but I said it anyway). Has anything like this ever happened to anyone else?
