Yes, I need to take more pics, but I'm waiting for 3 more plants to arrive.
I had good news this morning. Snack the shrimp successfully molted and was showing off his slightly larger version of hisself. Maybe all that tapping on the glass and yelling, "No! Bad fish!" every time I caught him eye-balling Snack worked. Hehe, probably not. I've never had a fish that could flash me the stinkeye before, but this one sure can.
I'm fairly convinced now that Shrimp #1 was the victim of an unsuccessful molt.
