So I switched from a 2x96watt PC fixture to a 6 bulb T5 fixture&since then my rics aren't looking so hot, they just look smaller. It may seem like a stupid question but I'm assuming I should move them farther down in my tank. Right now they are in the upper 1/2. I'm also wondering if I should be target feeding them? Right now I do dose the tank with phytoplankton 1-2 times a week but I'm wondering if they need more than that. If so how exactly should I feed them & with what? Any feedback would be appreciated.
