Hello,
I am wondering which fish species other than Apistogramma, Dicrossus, Taeniacara, Ivanacara, Biotoecus, etc. are able to grow and live without health problems in low conductivity (0-100 microSiemens, preferably around 20-30 microSiemens [10-15 ppm TDS] ) and low pH (under 5.5, preferably around 4.5).
For example discus breeders say they have to use very low conductivity for breeding but once the fry are swimming, they have to increase the conductivity up to a few hundreds of microSiemens or the fry will have skeletal deformations. Altum angelfish require similar conditions as Apistogramma to breed and even live (wild specimens especially), but german breeders always grow the fry in tap water too (which has pH 6.5-7.5 and TDS 200-250 ppm). So I don't know if it is healthy to grow even the altum fry in the extreme low parameters they need for the egg hatching process (which is fine for most Apistogramma).
I know species like Cardinal and Green Neons, most Nannostomus and some (or most?) Copella and Pyrrhulina species are found living together with even blackwater species of Apistogrammas. Are there other characins and any killifish, catfish, "oddball", bigger cichlid or even asian/african/australian species you know of that are living and breeding in such pure and acidic waters? Any that you kept for a long period or bred?
Thanks,
