I am making progress on the frozen brine shrimp, saw 4 of them eat them today. They are clearing out bbs fairly quickly too. I have split my grindal worms so they haven't had any of those in a couple of days, may be able to feed them tonite. I know they eat those too. I just read a thread that said they will graze on the bottom and I think they do at night. At least, the moss seems to be cleaner in the am's. What I really need to do is get a bigger piece of matted moss so I can gauge it better, nothing shows up on the white sand lol. So far I think I have 4 pairs, plus. But it is hard to count them all, they are so dodgy and you cannot see them in the grass. When I do the water change this week, I'm going to lift a lot of the plants so I can try to get a good count.
