discus breeding tank water depth
What's the ideal water depth for a breeding tank? I've got a 40-gallon setup with a pair of Discus, sand substrate, and a sponge filter. They're about 4 inches long, and I'm aiming to encourage spawning. Heard conflicting advice on whether shallow or deep water works better.

I keep mine at around 12 inches. Seems to work fine with my setup, which is similar to yours. Sand bottom, sponge filter, and a few Java ferns. They spawned last month without issues.

Re: discus breeding tank water depth
12 inches is a good starting point, but it depends on the fish's comfort. My pair prefers slightly deeper water, about 15 inches. They're in a 55-gallon with driftwood and floating plants. Maybe try adjusting gradually and see how they react?

Yep, gotta watch their behavior. Mine freaked out when I went too shallow, so I bumped it back up. Now they're chill at 14 inches with a bare bottom tank and a canister filter.

Re: discus breeding tank water depth
I've had success with 10-12 inches in a 30-gallon. Used a mix of sand and slate, plus a couple of Anubias. The key is keeping the water super clean, like daily 10% changes. They're picky about that when breeding.

Re: discus breeding tank water depth
Depth isn't the only factor. Water quality and temperature matter just as much. I keep mine at 84°F, pH around 6.5, and the depth at 13 inches. They've spawned three times this year in a 40-gallon with a HOB filter.

Re: discus breeding tank water depth
Thanks for the tips, everyone. I'll try lowering the water to 12 inches and see how they respond. Appreciate the help!

Re: discus breeding tank water depth
Yeah, Discus can be finicky. Mine took a few tries before they got it right. Now they're laying eggs every other week. Just keep the water pristine and don't mess with 'em too much.

Re: discus breeding tank water depth
Agreed. Less interference is better once they start showing breeding behavior. Mine don't like it when I hover too much.
