I just bought a brain and i am having trouble feeding it because of the flow in the area it is in. They need more of a flow don't they? Can they eat something bigger than the mysis i am trying to use or can they eat something bigger. would the best way to feed be by putting tupperware over it? Also what are the indicators of health it looks the same as it did when i bought...it seems to be a little bleached out and since i got it its gotten a little bit greener but i can't find any signs on this forum or on the internet of what to look for with health...
