Let us know how it goes. If it persists, test for phosphates. Sometimes they're the hidden culprit.

Biofilm can pop up if there's too much organic waste or low surface agitation. What's your feeding routine? Overfeeding might be the culprit. Also, check if your filter outflow is strong enough to break the surface tension.

Got it, gonna try Anubias first. Appreciate the help, y'all.

Thanks! How often do you fertilize yours, or do you skip it altogether?

Looking for some easy plants that can survive my neglect. My tank's got low light, no CO2, and I forget water changes sometimes. What's the toughest stuff out there?

Temp's one thing, but don't ignore tankmates. My discus were stressed until I removed the angelfish. Now it's just them and some tetras in the 75 gallon, temp at 84°F. They're way more relaxed.


Angels can be bullies, especially in smaller tanks. Discus do best with peaceful dither fish like ...

Mine are at 82°F. 40 gallon, sponge filter, no plants. They're small, maybe 2 inches. Not growing fast. Feeding flakes once a day. Should I raise the temp?


Definitely raise it. Juveniles need 86°F to grow properly. Also, upgrade to a bigger tank soon, 40 gallons is tight for discus long-term ...

Re: MALE or FEMALE

I'm curious about the discus' development. When can we expect to see the tube? Does it only appear during spawning, or is it visible at a certain age?

Re: MALE or FEMALE

It seems like sexing discus is quite the challenge. I was mistaken in thinking the tube could give us a clear answer. Would you mind sharing what led you to believe the white pigeon might be a female?

Hi everyone,

I'm new here and hoping for some assistance. I have 2 discus, both around 6" and 18 months old, and I'm trying to determine their sex. I've attached some photos for your reference.

Thanks for your help in advance.
