ok, my setup has 1 Red platy, the waters spects are all nitrate and ammonia are at 0 or near zero, the PH is rather low but a platy can take it, it is 6.8(i need to know how to raise it w/at home materials) i bought 1 sunset platy(femail possible pregnant b/c of the darkspot but that could be a natural spec) and a DEFINITELY pregnant swordtail, theres a large gravid spot inbetween the bottom fins, thye are currently adapting to the new waters but the platy in the tank by himself his always on the bottom and refuses to eat, he HAD ick and still does(put medicine and raised water temp at reasonable rate to help aid in the killing of the infestation, i got 6 baby snails to help clean the algea, i need to know howlong it will take for the swordtail to give birth, shes pretty big lengthwise i will get a picture of it soon but digi-cam batteries knocked out i bought the 2 new fish in hopes of cheering up my original platy by giving him a breeding opportunity. he occatioanlly goes to the top when i put cup in to sample the water, he enjoys being near it for some reason.
