Yes, they do look like true SAE to me.
I mentioned that to me it looks like the line is faintly there through the tail fin. I was hoping a response from the OP would help. Finding out if this was right after them going in, mine took a day or so to begin to get comfortable. An updated photo would be helpful though, @Ekhataerpthey don't look like SAE. black line does not extend past the caudal peduncle to the end of the tail. also, the black band is a little thinner and lighter, and less zigzagged (unless as aaron said they are new introductions).
do these guys eat algae including bba?
Thank you for your answer,this is the latest update,finally after 3 days they starting to eat green spot algae and bbaI mentioned that to me it looks like the line is faintly there through the tail fin.
