My tank is fairly new its about 2 months old; just finished my cycle about a month ago and the only thing I have had in my tank up until 2 days ago was a CUC. Went to my lfs and picked ip some molly’s to acclimate into the tank to test out the stability of my tank. All my water parameters are fine. Grabbed 3 molly’s 2 of them died in less than 24 hours and the 3rd is still alive in my tank. They look like fleas almost. Please help
