Hello I am new here. I have raised fish for a few years now and have never had this problem before. I got some Fancy Guppies all went real well for a while. I then got some more Guppies and added to the others , after I had added some stress coat. W hat seemed like over night they began dying one by one. Well, two of my preg. Guppies got caught in the plastic plants I had in the aquarium and I took the plants out. Well, I had three babies born now I have two babies one died. I took out half the water, replaced with fresh water adding stress coat, ick away beaceuse some had ick, but some were bulging which I thought could have been from the ick, added some aquarium salt which seemd to perk them up, but thie morning one of my two femals died, leaving me one male and one female and two babies. I took her outside and looked closely at her no spots, no swelling or bulging. Could some one please help me here. I have a Ph level of 5. Thanks in advance.
