That is pretty amazing,hey just a quick question,I keep almost all LPS corals but do have some pretty large leather corals,as those came with the tank when I bought it,but I also have A very few SPS corals and have had them about 3 months and all was well until a few days ago when my birds best completely lost its zooanthelle within hours,all parameters are good,all I can figure is maybe the leathers putting off toxins,I'm assuming but not sure. Anyone else ever kept SPS and softies like leathers successfully? I really don't care for the leathers now that I'm getting more experience and they are quite large,I'm debating getting rid of them,any one else had large leathers cause problems? Tank is 75 gallons.
