I just got my captive bred GF in mid November. So far the little guy is thriving.
If you need to have the eye spot to be successful to pair them then I would say you need to pass on the pics you showed in your post. Mine had a more distinct eye spot than yours, but it has started changing already.
Here’s a pic of mine w the spot. Even mine may not have the full and true “spot” necessary.
In unrelated GF news, but relevant to this thread-I ordered a juvenile blue line angel earlier this week. I think by time it is done w QT and in tank the two juveniles will be similar sizes or the blue line may be a hair larger.
I think adding them within 3.5 mos is pretty close to adding them at the same time.
What do you guys think?
