Any suggestions on what I should be feeding my Hillstream Loaches that I have in my Goldfish tank? I've been feeding them Yams, I put a couple about half inch slices in there. For the most part the Goldfish leave the yams alone, only nipping at it every once in awhile, but I'm looking for more variety for the Loaches their diet, while keeping my Goldfish from eating it first (I know it's probably near impossible). Also how often should I feed them the yams? I usually keep the yams in for 4-5 days or so that take them out for a few days then put more back in, repeat. And do they eat brown algae? I have a little in my tank that I want to clear out but won't if the Loaches will eat it (doesn't look like they have though). Thanks!
