That's a great collection for a first time owner. I was tempted to pick up those Orinos, but just don't have the space for them. How much blue are those zulies showing? My 8"er is really starting to color up and looks quite different from my 6 1/2" individual. I'm curious to see if yours develop along the same lines.
What size tank are you raising all these brutes in? And are you planning on keeping all of them or are you going to pick out a couple of each and sell off the rest?
