discus breeding water parameters
What's the ideal water temp for breeding Discus? My pair's in a 55g, pH 6.5, 0 ammonia, 0 nitrite, 10 nitrate, but they're not spawning. Using RO water with a TDS of 100, temp at 84°F. Tankmates are 6 cardinal tetras and a bristlenose pleco. Substrate is bare bottom, sponge filter, and a 200W heater. Feeding beef heart mix twice daily.
Re: discus breeding water parameters
84°F is good, but try bumping it to 86°F. Discus often need warmer water to trigger spawning. Also, check your KH—soft water below 3 dKH helps. I've had success with daily 20% water changes using RO mixed with a bit of tap to stabilize minerals. What's your lighting schedule? Dim lighting for 6-8 hours can mimic their natural environment.
Re: discus breeding water parameters
Yep, totally agree. My pair didn't spawn till I cranked the heat to 86°F and dropped the KH to 2. Also, try adding some almond leaves—gives 'em a weird vibe they dig. I use a 75g with a canister filter, temp at 86°F, pH 6.2, and they're laying eggs every two weeks now.boldo wrote: ↑Fri May 09, 2025 2:28 am 84°F is good, but try bumping it to 86°F.

Lighting's key too. I run a 12-hour cycle with a 2-hour dimming period at dawn/dusk. Discus are less stressed with gradual changes. Tank's a 60g, temp 85°F, pH 6.4, TDS 120. Sponge and canister filters, no substrate. Feed live blackworms once a week to condition them. Also, make sure your water changes are consistent—fluctuations can mess with their rhythm.
Re: discus breeding water parameters
yo, my discus only spawned when i cut the nitrates to 5 ppm. try adding more plants or upping water changes. i do 30% daily in my 40g breeder, temp 87°F, pH 6.3. no tankmates, just the pair. they're chillin' now, laying eggs every 10 days. also, beef heart's good but toss in some frozen brine shrimp for variety.
Re: discus breeding water parameters
How old are your Discus? Younger pairs might take longer to spawn. Mine didn't start till they were 18 months old. Tank's a 50g, temp 85°F, pH 6.5, TDS 150. I use a mix of RO and tap, with a KH of 2. Sponge filter only, and I feed a mix of beef heart, flakes, and freeze-dried tubifex. Lighting's on for 10 hours with a gradual ramp-up.
Re: discus breeding water parameters
Same here! Nitrates above 10 ppm stalled my pair for months. Now I run a heavily planted 55g, temp 86°F, pH 6.4, and nitrates stay below 5 ppm. Water changes every other day, 25%. They've spawned three times in two months. Also, try a darker background—seems to make 'em feel safer.kicks wrote: ↑Fri May 09, 2025 6:38 am yo, my discus only spawned when i cut the nitrates to 5 ppm. try adding more plants or upping water changes. i do 30% daily in my 40g breeder, temp 87°F, pH 6.3. no tankmates, just the pair. they're chillin' now, laying eggs every 10 days. also, beef heart's good but toss in some frozen brine shrimp for variety.
Re: discus breeding water parameters
Has anyone tried lowering the pH further? Mine spawned at pH 6.0, temp 85°F, TDS 80. Tank's a 75g with a sump, bare bottom, and driftwood. I feed a mix of frozen bloodworms and pellets. Lighting's on for 8 hours with a 1-hour dim period. Also, make sure your water changes are same temp—shocks can stress 'em out.

Re: discus breeding water parameters
Consistency's everything. My pair didn't spawn till I nailed down a strict routine: 50% water changes every Monday and Thursday, temp 86°F, pH 6.3. Tank's a 65g, TDS 100, no substrate. I use a canister filter and a powerhead for flow. Feed them four times a day—beef heart, flakes, and live brine shrimp. They've been spawning like clockwork for six months now.
Re: discus breeding water parameters
Don't overlook tankmates. My pair stopped spawning when I added tetras. Removed 'em, and bam—eggs within a week. Tank's a 50g, temp 85°F, pH 6.2, TDS 90. Bare bottom, sponge filter, and a single piece of driftwood. I feed a mix of frozen foods and pellets, with garlic guard twice a week. Lighting's on for 10 hours, but dimmed for the last two.
