The whole tank was all screwed up. I put the mirror up and that seemed to take care of the achilles, but then my two pyramids started going at each other, which I have never seen before.
The big Regal had started chasing the Rainfordi too. I think things are on their way back to normal.
I need to add some additional flow, no proof of this, but I think it helps. Been torn between the Gyre and the MP40's. I love the programmability of the MP40s and it would pair nicely with my radions, but the gyre seems like a great deal.
I've got a Tunze 6255 and 6155 and they aren't quite enough, IMHO.
