Lets be honest for a second. Keeping Discus is less behind a leisure interest and more past a high-stakes link in the manner of a activity of unconditionally expensive, agreed dramatic supermodels. Ive spent fifteen years staring at glass boxes, and if there is one situation Ive learned, its that these fishthe legendary Symphysodonwill locate any reason to break your heart. Usually, that reason starts when the broadcast they breathing in. If you are asking whats the ideal aquarium volume for a intellectual of Discus, you arent just asking nearly numbers. Youre asking how much room a diva needs to breathe.

I recall my first attempt. I had a 40-gallon breeder. I thought, "Hey, I'm a pro, I can handle the water changes." I put five youthful Discus in there. Within three months, the "Alpha" of the group, a pretty Pigeon Blood I named General Tso, had bullied the others into such a let pass of stress that they stopped eating. It was a disaster. Why? Because I ignored the fundamental physics of Discus fish tank sizing care.

Most old-school forums will say you the "ten gallons per fish" rule. Forget that. Its outdated. Its too simple. If you want a booming school of Discus, you dependence to think very nearly the ideal aquarium volume in terms of social dynamics and water stability. These fish are cichlids. They have attitudes.
