Nice fish! How are the fry?Oh my...
We'll have to disagree. These spawning discus are from a juwel 450 planted tank with cory cats, a large school of tetras, amano shrimp, and a lot of plants... In my living room
Also bright juwel led spectrum lights, 2 inches of substrate, (to hold the plants in place) co2 running at 1bps, and liquid ferts. To be honest with you I wouldn't keep them any other way.
Balancing the aquarium is more important than the aquarium setup itself.
