Dosent sound over stocked. Maybe up the number of cardinals, bigger numbers are better for the fish and massive cardinal schools look awweeeseome! :lol:
I just noticed this morning that my smaller peppered cory has a rather tall dorsal fin. I have heard of sail fin corys before and I was wondering if they are just a variety of peppered?
Umm, Cyclops are huge one eyed giants as far as I know so I dont think there will be a chance of babies eating them. :lol:
But then again you didnt say what type of babies. :lol:
Yeh I agree danios can handle anything. Or if you are looking for something more colour then maybe a livebearer of somekind. with them try and only all males or you may end up with a few too many fry.
Hope this helps.
