My duplicareus started spawning right away.
I don't think my group are not ready yet since I can't even sex yet. They all pretty much look alike ATM.
I am very fond of them. Lovely fish.
Yeah, I think they are pretty fish. Then again, that is probably why they are here and not in the store tank.
They like the pandas too. I see differences in their coloration, too.
What do you mean?

Do they like each other? And are you talking about the differences in the coloration between C.Panda and C.Duplicareus? Or among the group of C.Duplicareus?
Anyway, if I can get frys from them and C.Arcuatus. Maybe someday(hopefully not far in the future), I don't mind having big tank with C.Panda, C.Arcuatus and C.Duplicareus. That would be my Black and White group. And hint of orange.
Although I already have orange fin group, with my C.Sterbai and Albino Bristlenose pair(I know one is a male but 2nd one I am not sure yet. But I have 4 more in other tank so should have a female or 2. They are still too young to sex them) They could join with Albino C.Sterbai in bigger tank after they are quarantined. Then again, they maybe kept seperate, I don't know yet. I guess I'll wait and see how they fit.
And I will have some Green, the Laser Green Neon color soon,

I will probably keep them in dark substrate with green plants(probably Java Fern, Moss and Anubias since it probably is a lower light tank) In the dark green tank. Of course, first I need to quarantine all the fish coiming in.
I could have Albino tank also if I want to in the future with Albino Sterbai, ABN and Lutino Neon Tetras(which is not technically Albino since they do have black eyes and they are more selectively bred color morph but close enough.)
And I don't know where the C.Similis fit yet, smudge spot group? Then I only have them as smudge spot fish but Panda have spot also but different color. I might keep them with young Panda frys before sexually matured.
Lots of possibilities with more fish with more combinations. I think after next week, I will fill all the tank I have with fish except the 55G I was planning to build the show tank but probably gonna be end up with fry growing tank when the frys in 20L become too big in there. I have them running already with filter and some plants.
Still I have lots of shuffling to do in next few months. But it's cool. Lots of tank with many Corys. From frys, young and breeders. And more colors.
Can't wait those new Pre~~tty fish. And the green ones will become the most expensive fish I will have after they get here. At the moment, it is C.Duplicareus.
