Thanks, all my water numbers are
pH 7.6; Amm 0; Nitr 0; but Nitra spiked to 10 with this recent tank move which put my plant filter into shock for a couple days. I have two female black molly's first that were not pregnant then later two male sailfin platinum molly's and they have been courting for 2.5 months strait and while the black molly's were getting bigger and rounder now suddenly their bottoms look like cargo ships so big that their black has changed to silver as the scales are stretching. Look like I got the 120 just in time to move my bigger fish to it ASAP.
