I have to agree with Joel - kinda. I had a spawn that fungused extremely quickly at pH of 7.0 However at pH 6.7 with an airstone only - no meth blue I estimate a better than 70% hatch rate. I did however get a large number of belly sliders (airstone too vigorous?) 55 free swimming:15 belly sliders. At 3 weeks after spawning I have more than 40 fry. The biggest is approx 1cm. My water is tap water treated with Seachem Acid Buffer and a small amount of peat in the filter. steph ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@majordomo.pobox.com.
