Who Gives A Fish Forums

I've got sand substrate and a mix of Java Fern and Anubias. Lighting is basic LED, no CO2. The plants are growing slow but steady. The Corys seem to love digging in the sand.

Thanks for the input. I do weekly 25% water changes, and nitrates stay under 20 ppm. The Angels are still juveniles, so I'll keep an eye on their behavior. Maybe I'll hold off on adding anything else for now.

I've got a 55 gallon tank with 10 Neon Tetras, 6 Corydoras, and a pair of Angelfish. The tank's been running for about 6 months, but I'm worried I might be pushing the stocking limits. How do you guys gauge when enough is enough?
