Plakats or Emeralds?

[Styx]

I'm thinking they're plakats from how aggressive they seem. But I love them no matter what they are. What do you think?

Pegosus (can't tell from photos, but I think he has the cutest face I've ever seen on a fish):

Zosimus:

Next, Super Detla or just Delta tail? What do you all think his tail type is?
Ekaitz:

I appologize if they're too large. I have a shoulder ache from holding my dog in my lap...

Plakats and a delta, I'd say. That second guy is a real beaut!

Thanks!

Yeah, I was told by the person I got them from they were Emeralds, but I was doubtful. Either way, I loves them. :3

Is "emaralds" the new name for smaragdina now?

I’ve never known them by any other name. That’s what the encyclopedia of Fresh Water Aquarium fish said their common name was.
