Another vote for NLS. I have a tank of clown loaches just fed on NLS and another fed with a variety (mainly a bunch of hikari carnivore wafers, algae wafers, and massivore that I got for free). Both tanks have healthy fish but the coloration of the clowns in the NLS is noticably brighter. One of my friends came by today and asked me why the clowns in the tank in my room are so much more colorful... cough... cough... NLS. The tanks around my house normally get fed by my dad once a day in the morning, but I feed the ones in my room. All the fish we own would get NLS but we gotta get rid of the "junk food" first. I hate it when my dad throws in some of the cheap koi pellets for the koi and goldfish in our koi pond into the big display tank outside my room... His reasoning is that the fish need their veggies too... lol. It's hard explaining to him that NLS has all the veggies they need even after showing him the list of fruit and vegtable extracts printed on the ingredients list on the side of the NLS container. He also insits on buying cheapy koi pellets for his koi and goldfish in our pond even though I have some nice fish in the pond too (that deserve much better!).
