Thank you guys so much for the fast replies! I just need the black neon tetra reference now.
Interesting info re the cories. I don't know what you mean by 3 lines exactly, but the julii has spots when the trilineatus has lines so comparing with my pic it is definitely the trilineatus. Brian from the Goldfish Bowl had said this too so I would believe him (been in the industry 40 years).
edit: thanks pegasus i just saw your reply now, i sat writing my reply while in the meantime you made your post.
