Pet's info: Fish | Freshwater Fish | Female | unspayed
Hey so I currently have a spear 200 litre tank since I moved my Goldfish to a 500 litre tank. I used to breed guppies and I want to do it again, so I was thinking of filling my 200 litre tank with guppies my question is how many guppies will fit in the 200 litre tank, thx

Thanks for reaching out. The general rule of thumb with good filtration is to have 1 " fish per 12 liters (3 gallons) of water. So starting with 10-15 should be good, but remember babies increase the bioload significantly, so continue to monitor water quality and allow your biological filter time to respond. Good luck.
