Rehomed, due to not being the direction I had originally wanted to go. I'm still surprised at how passive Boomer was. Anytime I fed the SD went crazy like piraña and Boomer would retreat to the other side.
Well, I am back in CA cichlids. Purchased 3 Rainbow Cichlids yesterday, all about 3in. I know that I have a pair as there were eggs being guarded by one in a broken clay pot in the tank at the LFS. Now just need to figure out which tank will be their home after QT.
