Flag cichlid /american flag fish confusion

[gmaniac]

Hi all,

In my attempts to battle hair algae (green filamentous, attaches to plants,
rocks, driftwood, comes off easy with rubbing) , I'm trying to control the
nutrient balance in my new pretty heavily planted 75G (I have trace
phosphates and nitrates, ph 6.5 with CO2, 3.5 WPG) . On good advice, I got
some black mollies that certainly help, but they seem to be chowing down on
the Mayaca sellowiana as well...so they might be leaving soon. The SAE's
and Oto's aren't doing to much with the hair algae at present

I scoured the APD archives and then went to Petco to get some
America/Florida flag fish. First time I went, I saw them labeled as flag
cichlids and thought they must be different than AFF's. I went back home
and looked on the web and then somehow convinced myself that Petco had
"mislabeled them". I bought two of them and got them in the tank....they
are getting acclimated now, but I now realize that I may have made a
mistake, and they are Flag cichlids after all.... I looked at more pics of
both fish on the web and it is not easy to tell the difference to my eye!
I think that AFF's may have a light central yellow whereas the Flag cichlids
(Laetacara curviceps or acara curviceps, not sure which I have) dont have
that coloration, in addition to the black coloration on the superior
(topmost ) fin of the Flag cichlid

So now I'm stuck in an unsure state and meanwhile the hair algae grows as I
battle it with nutrient competition, water changes ,etc. Anyone have any
thoughts on this ...please tell me this is an honest mistake so I dont feel
so stupid....
Also, anyone have any leads on shops or breeders where I can get AFF/FFF
(other than the AKA) ? I would pay for shipping, and trade if I had anything of value. I know algae eaters aren't the ultimate solution,
but they would certainly make me feel better that something is controlling
this stuff, while equilibrium kicks in.

thanks in advance!!
