He's not eating!:( I put some Bloodworms in the tank, (his fav food!) and he didn't touch them. He's now starting to protrude something like Ash mentioned earlier (not a worm, more like intestine) from his rear. I am making an appointment with a fish vet Dr Jim Greenwood first thing. I've had my water tested by a reputable aquarium, and the contdions are all good, other than the GH being a little low, although from what i've read, these guys ain't that fussy. It was recommended for me to do a 15- 20% water change and add a water conditioner to raise the GH level. I was told you can't test for everything and they truley believe the problem is enviromental. I do not agree. If it was, my other fish would be showing similar signs? The aquarium told me the GH needs to be around 180ppm (10 drops), although in all the fact sheets I have read (to get as much info I can) tells me the GH should be 15 drops. I'm getting so confused & frustrated
