Hello there! Sorry if this has been answered before but I want clarification that between Julii, Trilineatus, and Leopardus are three different species. My own research points to:
1: Julii have finer spots on their head, rounded face?
2: Trilineatus have connected patterning along side the the three stripes that they have, from my own fish tank they have a rounded face as their barbels point more straight down.
3: Leopardus maybe have some connected patterning but their face comes to a point which is signified by the longer face and their barbels point more at an angle to the ground.
I'm trying to figure it out because I did buy 6 corys about a month ago and had a hunch that they are not Trilineatus but actually Leopardus. Which if they are would make more sense why my 2 Trilineatus(?) don't really follow them around as much. It's hard to tell because they are comfortable meandering about the tank most of the time.
Here are the two I believe to be Trilineatus as I've had them the longest. (8 Months)
Now here are some of the 6 I got a month ago.
Sorry about the clutter on the supposed Leopardus corys I had just dropped food in for them. I'm seeing a longer face?
Are there any long term effects of 6 Leopardus and 2 Trilineatus?
