I only have one two inch molly, feed him one flake a day and i do 15% water changes weekly (1.5 gallons) ive never had the tank without atleast one fish in there. So what should i do go get another fish kr add in conditioners?
Well with a WC that small it shouldnt remove too much beneficial bacteria, but with only one fish in there the colony of beneficial bacteria would be rather small, the rest would have died off because there isnt much waste in the tank. So when you go to add fish, do it slowly over a couple weeks. One or two fish at a time.
