Tedrock Posted November 10, 2020 Share Posted November 10, 2020 Can you take a look at these pictures and let me know if these fish are true Julii Corydoras? I have read many places on the internet and I just get more confused. Any help would be appreciated. Many thanks Tedrock 1 Link to comment Share on other sites More sharing options...

Ruud Posted November 10, 2020 Share Posted November 10, 2020 (edited) Most Corydoras that are sold as Jullii's are actually the more common Trilineatus though it is very hard to tell the difference at times. To my amateur eye, yours look more like Trilineatus to me, though it has been a long time since I had mine. Jullii's have a more spotted pattern instead of the lines, hence my opinion.

Tedrock Posted November 10, 2020 Author Share Posted November 10, 2020 This is frustrating I bought 10 to start a breeding group and the seller swore the were true Julii. I was nervous considering the investment but I should have known better. They are good cory’s I just am disappointed. Link to comment Share on other sites More sharing options...

C. trilineatus have reticulation especially on the head. Not to hard to spot once it has been explained. 1 Link to comment Share on other sites More sharing options...
Ruud Posted November 10, 2020 Share Posted November 10, 2020 With reticulation (had to google translate that and still came inconclusive) I think you mean the line pattern instead of the dotted pattern @Daniel? I understand your disappointment @Tedrock but they are good and healthy looking Cory's . The Trilineatus was the first Cory I held (followed by Gold laser, Green laser and Brochis splendid) and they are very nice. But yes it always sucks if you get something else than you ordered. 1 Link to comment Share on other sites More sharing options...
Daniel Posted November 10, 2020 Share Posted November 10, 2020 Reticulation is like a grid of connected lines or dots. The phrase "reticulating splines" still rings in my head from playing SimCity 2000 to many times many years ago. Link to comment Share on other sites More sharing options...
Marc Posted November 11, 2020 Share Posted November 11, 2020 (edited) I purchased mine as Corydoras Julii from Aqua Huna. Whatever they are I am happy with them. They look very similar to yours. Sorry for the diatom algae on the tank blurring the shot a bit. Edited November 11, 2020 by Marc punctuation Link to comment Share on other sites More sharing options...
Tedrock Posted November 12, 2020 Author Share Posted November 12, 2020 These are more fish from the same group. Link to comment Share on other sites More sharing options...
Andy's Fish Den Posted November 12, 2020 Share Posted November 12, 2020 Many time Corydoras are imported as one thing, and that name will stick with them all through the supply chain to the LFS. Most of the times, the LFS has no clue what they are, unless there happens to be someone working that is good at identifying the fish. I've imported fish with my local club and ordered one type of cory and ended up with actually three different species in the bag. If they had gone to an LFS they all probably would have been sold under the name they received them as. 1 Link to comment Share on other sites More sharing options...
Ruud Posted November 12, 2020 Share Posted November 12, 2020 The top one looks to me more like a Jullii @Tedrock. Also agree with what @Andy's Fish Den says. One of the reason I have never ordered fish without picking them myself, though that might change soon considering availability here in Spain. 1 Link to comment Share on other sites More sharing options...

Pretty sure this one (top cory in the second pic) is corydoras similis, the smudge spot corydoras. A beautiful cory in its own right! But not a julii. The smudge around the base of the tail will get a purple-ish sheen in the right light. 1 1 Link to comment Share on other sites More sharing options...
