Nice pickup! That female was actually mine. It's a cyanoguttatus and I'm assuming the male is the same. it's between 4 and 5 inches if i remember correctly. I dropped off a breeding pair (male Carpintis and your female Cyanoguttatus) 3 weeks ago at ocean blue. I guess he either separated them or someone had bought the carpintis. It's a nice female though. I only fed it bio gold pellets, gold pellets, and frozen krill and it breeds all the time.
