I am treating my 29 gal tank for ich. The only casualties I have had are three pregnant female guppies, all of which have died in the past week or so, when I was sure they were on the verge of giving birth. Do you think this is directly related to the ich and the pregnancy? Or maybe it is due to the fact I have put my temp up to around 81 degrees to help combat the ich? All my other fish seem fine, the white spots have gone on the 3 fish which had them, they are eating fine, water parameters are fine etc. None of the three fish which died had showed any visible signs of ich.
I have 1 large pregnant guppy, 1 pregnant balloon molly and 1 pregnant platy, also 5 large female guppy fry, some of which are also pregnant. Do I need to remove these fish from the tank before something happens to them nearer birth too?
