Thanks for your help. My water tends to be slightly acidic and the hardness is about 80 ppm. So, it sounds like its good enough to keep the checkerboards, but not to breed them. The checkerboards, by the way were in a tank marked "miscellaneous fish - $1.29 each." I haven't been back to the store in several weeks so I don't know if there are any left. They were small & the fins were kind of chewed up. At home, however, they seem to be coming along well. On the other fish, I know they are not Steindachneri since I have been keeping Steindachneri. 3 of the four mystery fish unfortunately died in short order. The other fish in the tank, however, showed no ill effects.

These fish are hardy in the aquarium - as long as your water isn't too hard (> 10º dGH) and acid (< pH 7). Otherwise they are more susceptible to diseases & parasites. If you can't provide moderately soft, acid, water then you'll have problems with them. As for breeding, the other replies are right on. As for you unidentified apistos, if they came in with Nannacara anomala then they are probably A. steindachneri. This species once was erroneously IDd as "A. ortmanni", but the true ortmanni is very different. They are the bluish species that most often comes in with Nannacara.

Here is my question: Linke & Staeck make them sound very delicate & challenging. Are they really that difficult to keep ? Are they that hard to breed as well? I do not use r/o water. For the moment, they seem happy. One has clearly begun to develop the lyre tail characteristic of males. > > My LFS has lately been selling unmarked "dward cichlids" for $2 each. Some are clearly nannacaras, but I have a bunch that I can't quite identify. When I bought them they had five or six pronounced vertical bands. These have now faded and they have a yellowish background (one is blueish) and black spots that appear like a broken up lateral band. The have black stripes above & below their eyes. One has black ventral fins that make me think she is a female. All are fairly small and nondescript. > > The only guess the guy who sold them had was Ortmanni.
