I have just gotten a pair of A. cruzi also. I have basically the same questions and will tell you that they are currently in soft water generated from a home softening unit which means that there is a pretty high content of disolved solids but relatively low GH. The KH and pH are probably relatively high at the moment but I am planning a regimen of water changes with RO water to reduce the total disolved solids and will add Peat extract or "Waters of the World" for South America. I have hatchets as dithers and I may at some point add a zebra pleco to the tank. I have a clay "cave" for them which should allow seclusion if they wish to spawn. Thanks in advance for any information you all might provide. At 12:53 PM 1/20/98 -0600, Lilia wrote: > >Recently I got a pair of A.cruzi. I can not find any specific information >on keeping them. The only thing I found is what they belong to A.regini >(sp?) group. And sales person (very good one) said they are "hardy".
