Who Gives A Fish Forums

Aight, so Cardinals it is. My LFS has 'em cheap, so I'm gonna grab a dozen. Tank's at 82°F, got a bunch of plants and a sand substrate. Gonna do the drip thing like pores said. Hope my Discus don't freak out.

Sounds like you're on the right track. Just one thing—make sure your Tetras are well-fed before adding them. Hungry Tetras might nip at Discus slime coats. I feed mine brine shrimp before introductions, and it's never been an issue. Good luck!
