Yes, for the most part. The photo in Richter, p 115 top left, is a good
representation of a laterally displaying male A. ortmanni

A. regani, maybe A. gossei, A. geisleri, A. sp. Smaragd, A. sp. Sao Gabriel/Alto
Negro, A. sp. New Blue/Blue/Steel Blue (a probable hybrid).

Surprising but not impossible, but most fish sold commercially as A. ortmanni are
actually A. steindachneri. Yours don't sound like it, however, since they have a
long caudal spot while steindachneri has an oval spot that usually doesn't cover
more than the center 1/3 of the caudal peduncle height.

Regani-group species are rather isomorphic. Once they are fully mature the males
have more color and normally have pointed tips on the caudal and anal fins. The
ventral fins are larger on males and the front edge is black on females.

Probably. I'd remove about 1/2 of the rams and see how it works out. It's a good
excuse for buying another tank!

Hardness & pH should be OK for maintenance. I'd lower the KH to 1 or 2º if it is
above this range (I doubt it is on you volcanic island home). A pH in the low 6
range would be better for breeding purposes.

Grow the up and enjoy them.
