I thought I best join this lovely site since its held a few answers for me in my google searches...
I'm a new aquarist, well, 9 months in. I have two smallish tanks holding a few guppies, two of whom appear pregnant and will soon to multiply!
I've had to "refresh and restart" my bigger tank which had some sick fish in it
so I'm cycling it now with the two pregnant ladies, but doing frequent water changes so they don't get too stressed. My ammonia seem to be holding around the .25 mark and I'm 3 weeks in. The girls seem happy compared to being in the other tank where the boys were constantly at them. Ugh males.. Ha
Nice to meet you all!
