I'm tempted to get another Kole as well, very active friendly fish.
My next stocking will probably be 4 blue reef chromis. I'm still unsure about more tangs, but I'd want larger ones this time since the yellow one I have is a bit of a bully. lol
I'm working on getting a 20 something gallon tank with stand so I'm hoping to make that the official QT.
On another note, I purchased a yellow watchman for my cube, and wouldnt ya know it the clowns will not leave it alone. I may have to move the clowns back into the 125g. Or move the watchman into the pico lol
I've talked to alot of people about my problems and most of them said it doesnt appear to be velvet and we know it's not ich. Everyone I spoke with, on this forum and in several fish stores are clueless how the fish died so swiftly cause velvet doesnt kill in 24 hrs. Some have suggested trying a different store since every fish but the clowns came from the same store.
So far last 4 fish are still alive and kicking and eating me out of house and home. lol
Just thinking this through in my head and hoping I'll come to a good solution.
