uh... well.. I went to walmart for painters tape, stopped by the pet section for some air stones, walked past the tanks that appear have a very healthy stock of dead fish..I decided to peak in the quarter sized hole of algae and a very tiny, very sick, VERY UGLY tiger oscar is floating around next to his dead buddy. I don't really care for cichlids let alone tiger oscars, but I do have a respect for fish.I can pick it up in the morning (I was going to buy it now but I had to resist and ask the pros here 1st) hes a fighter but hes hurting. I have an established 20 gal guppy tank (not to be-little you guppy fans) but eating few might help. Is he too far gone? I don't even know what I would do with him, but I don't want to watch him dying every time I go to walmart. I started adding salt to the guppy tank and raising temp. Thanks in adv. for any opinions.
