I have been feeding most of my fish once a day, barbs, tetras, corys, bristlenose and loaches. Will this be alright for the apistos? Or, do they require different care? I'm using frozen bloodworms and flake right now. What do you think about live tubifex? Some people say they're fine and some say they carry disease. I feed live tubifex a couple of times a month and haven't had any problems yet.
