I have a 20G long tank with 2 filters, an Aquaclear 50 and a Marineland Penguin 150G. In the tank, I have 5 guppies, an Albino Cory Catfish, and a Julii Cory Catfish. I'm getting 3 more of each Cory Catfish soon, to give them friends, but I want a new school of fish that swim around the middle. They have to be at least 1 1/2 inch because otherwise the Aquaclear filter will suck them up, and I like the bigger ones anyway. Are there any suggestions for what fish? I also want something natural looking, not like the neon or glow light tetras. They're beautiful, but not what I'm looking for.
And, I was thinking of adding live plants to my tank, but it isn't by a window of any kind, so it'd have to survive off of my LED
light. Are there any plants that will do that? Thanks!
