If you want to count the tail spot as a stripe, then you have to count it on the fish in question, as well.......that would make 2 stripes on the caudal peduncle, as aposed to only one on a convict. It's still the very same distinction.
I agree, the fish could very well be a hybrid CA...... one that superfiscially resembles an Austroloheros species
I don't think the anal fin on the fish in question, looks at all like a convict's. I count no more then 4-5 anal spines; the spine area just doesn't seem long enough to be a convict. Then again, the pictures are a little blurry.
I still think it's an Austroloheros species. It's got the shape of one, the stripes on one, the color of one and the eye of one. But time will tell.
