Alright everyone, so here's the scoop.
Right now I have a 20 gal long tank stocked with my chosen cycling fish; four regular Zebra Danios. So far they've all survived for a little more then a week without any obvious problems. As far as I can tell, at the moment they are all perfectly happy and acting as I imagine Zebra's should, energetic, curious, and playful.
As soon as I deem the tank successfully cycled I plan on adding a second species. Surfing the web, I've decided that I think a Corydoras Catfish would be a positive addition to my tank. But before I even think about going about this, I have a few questions I'd love if someone could answer.
1.) Are Cory cat's a species that would require a large amount of the same species to be kept content? Seeing as I only have a 20 gal, I planned on keeping a maximum of two. Would this be alright, or is this too few?
2.) With four Zebra's, would it be likely that any Cory's put into the tank may be harassed by my speedy little beginning fish? Since they were there first, I'm almost afraid they'll become territorial, especially the one I named Alpha. She's not aggressive, she chases, but never nips. She simply enjoys her space.
3.) I've read that Cory's like sinking pellets. Since I am currently feeding my Zebras small amounts of flake twice a day six days a week, how often would I be offering a Cory cat some sinking pellets?
Any and all advice is greatly appreciated. Like I mentioned, I still have some time before it's right to add a few more fish, but I figured there would be no harm in curing my curiosity's early.
