Discus fry tank heater choice

[Raven]

Setting up a fry tank for my Discus and need advice on heaters. Current tank is 20 gallons, bare bottom, sponge filter, temp at 84°F. Heater I have is sketchy, keeps fluctuating. What's a reliable brand for fry tanks? Prefer something with precise control.

I've had good luck with Eheim Jager for fry tanks. They're solid, hold temp steady, and won't break the bank. My 20-gallon fry tank runs at 85°F with zero swings. Just make sure you get the right wattage, 100W should cut it for your setup.

Seconding Eheim Jager. Used one for my last batch of fry, no issues. Also, consider a backup thermometer. I've seen heaters fail even from good brands. My tank's got a digital one stuck to the side, gives me peace of mind.

If you wanna splurge, go for a Cobalt Neo-Therm. They're pricier but super accurate and slim. My fry tank's been at 84.5°F for months with no tweaks. Plus, the LED display is handy for quick checks without opening the hood.

Anyone tried the Fluval E series? I'm running one in my 30-gallon community tank, but curious how it handles fry temps. My Discus are adults, so I keep it at 82°F, but heard fry need tighter control.

I've used the Fluval E 100W in a 20-gallon fry tank. It's decent, but the calibration was off by 1°F out of the box. Had to adjust it manually. Not a dealbreaker, but worth noting.

What's the ideal temp range for Discus fry? I've heard 84–86°F, but some say 82°F is fine. My tank's at 83°F, but growth seems slow.

Stick to 84–86°F for fry. Lower temps slow metabolism, which can stunt growth. My fry tank's at 85°F, and they're packing on size fast. Also, feed 'em small amounts 4–5 times a day if you aren't already.

I've got a cheap Aqueon in my quarantine tank, and it's been surprisingly reliable. Not as fancy as the others mentioned, but it gets the job done. Just double-check the temp with a separate thermometer, 'cause the built-in dial can be a bit off.

Heater drama is the worst. Had one fry batch wiped out because a no-name heater spiked to 90°F overnight. Now I only trust brands with fail-safes. Eheim and Cobalt are my go-tos, like others said. Also, always unplug during water changes—fried one heater that way, lol.
