Might wanna test for dissolved oxygen levels. Had a similar issue once, turned out the canister filter wasn't agitating the surface enough.

Thanks for all the advice, everyone. I'm gonna go with sand and keep it shallow. Appreciate the help!

I'm setting up a new 75-gallon tank for my Discus and can't decide between gravel or sand. I've heard sand is better for their natural behavior, but gravel is easier to clean. Anyone have experience with both?

I've noticed my Discus prefer tanks with minimal decor. Too much clutter stresses them. A few pieces of driftwood and some plants are enough.

Have you made any recent changes to the tank? New decor, filter media, or tankmates? Sometimes even small changes can stress them out and affect their appetite. Also, how's their behavior otherwise? Any signs of illness?

If you're doing everything right and they're still not growing, it might be worth isolating one or two in a smaller tank with perfect conditions. Sometimes they just need a reset to kickstart growth.

Have you checked for internal parasites? Sometimes they eat fine but don't grow because of worms. Metroplex in the food might help. Also, what's the filter type? Canister filters are best for keeping the water pristine, which is key for growth.

Consistency in their shape is key. A healthy Discus should have a round, symmetrical body. Avoid any with visible deformities or uneven growth. My tank's got a T5 light setup, and I've noticed better coloration since I upgraded from LED. Also, ensure the store's water params match yours to avoid ...

Observe their behavior with other fish. Aggression or extreme shyness can indicate stress or illness. My Discus are in a 60-gallon with a mix of tetras and corydoras, and they're chill with tankmates. The store's feeding routine matters too—ask what they're fed and how often. Sudden diet changes can ...
