I have two: crispa and orange skunk, percs and magnifica. I do like the fact that they are natural combos and there is an immediate affinity with the host. In the past I've kept non-natural combos, eg occellaris with BTAs and though they decided to be hosted, there was never the bond I've observed in natural combos. I have a pair of maroons that are also beautiful, spawn all the time and look great in their 7 BTAs, but the female has brought blood on several occasions when I'm working on something in the tank. I find their disposition annoying. The female is just a little too sassy, in my opinion ; )
