How mAny Male Guppies In A 55 Gal Tank?

DanDan

My tank has been set up for 3 months and all it have in it right now is 8 emerald green cory catfish. I want to add all male guppies but am unsure of how many I should add. The tank temp is 76 degrees and running two aquaclear 50 filters.

I would not add them all at once as you don't want to create a mini cycle but you can have a lot I would say at least 30 probably more.

yeah I would agree 30ish.. 35-40 if you wanna push it. Assuming nothing else but the corys. Also as K19 mentioned dont add them all at once. Do like 6 or so a week.

I see your tank has been set up for 3 months... but you are sure it actually cycled right?
