Hi, I am new to this site and I have a quick question about stocking options for my 125 gallon tank. I currently have a oscar about 10 inches in my 75 gallon which I would like to transfer to my new 125. I have a fluval FX6 hooked up to it and regulary do waterchanges about once a week. My local fish store said that 3 oscars total with proper water changes would work in my 125. I am curious if any of you guys had opinions on that or different options for tank mates as I dont want to over crowed or stress my fish out. Thank you guys for your help!
