Who Gives A Fish Forums

I've got a 40-gallon tank with moderate flow, running AI Prime lights at 50%. What are the best options for low-light corals? I've tried Zoanthids but they're not thriving.

Mushrooms and Leather Corals are great for low light. I've had success with Ricordea and Toadstools in similar conditions. What's your nitrate level? They can be sensitive to higher nutrients.

Yep, Mushrooms are a solid pick. Also, check out Gorgonians if you're into non-photosynthetic options. Just gotta feed 'em regularly. What's your feeding routine like?

I'd throw in some Green Star Polyps too. They're hardy as heck and spread like crazy, even in lower light. Plus, they add a nice pop of color.

Thanks for the suggestions. Nitrates are around 10 ppm, and I feed twice a week with frozen mysis. I'll look into Gorgonians and Green Star Polyps.

If you're up for a challenge, try some Acans. They can handle lower light if you spot-feed 'em. Just don't blast 'em with flow, they'll retract and sulk.

Yo, don't sleep on Xenia either. They pulse like crazy and don't need much light. Just keep an eye on 'em, they can take over if you're not careful.

Agreed, Xenia's a good call but definitely needs space. Maybe isolate it on a separate rock.

I've had luck with Kenya Trees in low light. They're kinda boring but super easy to care for. Just don't expect 'em to wow anyone.

What about Palythoas? They're similar to Zoas but might handle your light better. Just watch out for the toxins if you frag 'em.
