Yeah, they're expensive. I'd be happy to get a (cheaper) CT instead of an ST though. Looks almost exactly the same to me and a lot of guys who keep dats say it's really hard to tell them apart.
To me, IT are only worth keeping if they're stable. Too often though, they become unstable for no good reason. You can have perfect water conditions and the fish will seem healthy, but he's dark black all of the time. That's why I think NTT is better. NTT can be unstable too, but they are much much more likely to be stable and have a good yellow/orange color than ITs. OP's indo dat looks pretty nice though.
