I've been requested to show some pics of my diminutus I have now. I grabbed my camera phone and took a few snaps. Crappy pics, but I'll try to get some better ones later. PH plays a large factor in color for these. When they arrived they were bluish. Now in 7+ the adults have turned color. The males are now tannish and the fems are blackish- this is in my 7+ ph. I'm theorizing the blue color is due to low ph stressing them somewhat from black to blue, BUT having said that- they seem to breed well in both ph. You'd think if they were stressed they'd stop breeding. So, who knows? The juvies are blue right now, but I'm guessing it is because they have thin shells atm.
This is mom when she arrived. Unfortunately, she wasn't out and about so no pic right now of her color:
This is dad currently in ph 7+. Note he is now tan.
These are a couple pics of the blue juvies:
Adults are as big as dwarf shrimp, and smaller than cpo. The babies can be compared to newborn dwarf shrimp as well. The blue color would be perfect in crystal params, I'm guessing. I plan to test my theory soon.
