I have a spare 10g tank that i want to set up for dwarf puffers and maybe a trio of otos. I am going to cycle it with platys as i did my tank with these last time and it worked fine. My question is how many platys shall i put in so that the bio load will be approximatly the same when i swap these out and put my puffers in? I know alot of you don't agree with fish in cycles but that is how i am going to do it sorry!
