Will they be able to manage in hard water - pH 7.0-8.0, GH 15+ and about 1000+ mS?
Does it changes between the species?

Are they compatible with calm smaller fish and other dwarfs like Apistos an Dicros?

Yes, different species have different requirements. You will be able to keep many species under the parameters you've listed but, they will not spawn.

I would not keep them with any fish smaller than they are. Anything smaller than a cardinal tetra will probably become dinner at some point.

Thanks Rahul,
What about this species:
Crenicichla compressiceps
Crenicichla orange
Crenicichla regani


I guess you meant that they will eat any fish smaller enough to fit their mouth (what basically correct for most of the fish), but will they do well with Tetras and other small fish that are smaller than them in body size, though large enough for not be swallowed wholly? And could they possibly harass them?

Crenicichla compressiceps: pH 6.0 to 6.5 / dGH 1º (Stawikowski & Warzel 1991).

C. regani: Parameters Tapajós river: pH 4.8 / conductivity 10 uS/cm!! (Kilian 1992).

May be C. heckeli that it tolerates pH of 7.5.

Rafael.
