Tank update...getting lots of softies that I see lots of negative nellies....Yup I got a Kenya tree, red discomia shroom, green ricordea, blue striped shroom, Blue spotted Red Mushroom (superman) GSP I put on a rock island...Some Zoas. I feel the negative nellies don't "work" on their tanks and don't frag or cleanup soon enough that the sofies overrun the tank. Would you agree or am I in for a tank of overgrowth mess?
