i was wondering about cajuns myself. I have ..7 allenis that are all blue. And i think i'm getting a CPO next since i love their bright orange. I think it would work well with all the greens in the tank and whatever color gravel i'm choosing, the orange will definitely pop. That being said, i saw some beautiful cajuns too.
have u seen blue marmokrebs? Those are the self cloning ones. I have a few of those too. They're a mix between brown and blue and since mine are all so small ,i can't see any blue yet. Are you buying from aquabid? if you're interested in marmokrebs, i can maybe pick up some for u at in my area. But i've never shipped them before so...they were $10 each.
