Unless you have a dna testing kit, your properly going to struggle to tell the difference between a sagittae or citrinellus, so I would go for a sagittae.Yes the 125 is for a pair of Amphilophus (whichever I end up getting) and the plan is to end up with a pair in there and that's it. I have been considering the barred Midas but really like the darker orange color. Just feel like I may be waiting forever if I don't decide on something else
