Red/Orange Flakes Everywhere! What are they?

[Lizardgi]

Hello, since my tank 125 gallon was moved and setup last week, I've noticed more and more of these red/orange flakes in the tank. They stick on the glass (but are easily brushed off) and rock mostly. They look like half popcorn hulls. What are they?

What you have there is flat worms.They are a pest that can become a huge problem.
Get some flatworm exit and follow the directions.

Thanks for the quick reply! These little buggers just exploded in a few days. Looks like I'll be declaring war on them on Saturday around 3pm. I've got to order in some Flatworm Exit and make some extra saltwater first. Would there be any benefit to setting up a separate quarantine tank for my clown and brittle star during the treatment, or should I not even bother and just be vigilant with the extra carbon and water changes?

Yep, definitely flat worms. Try and siphon as many out as many as you can before you use it.

Consider a 50% water change after using flatworm eXit.

YMMV, but i couldn't get any siphoned out before using the flatworm exit.
But the flatworm exit worked the mutts nuts. I did have to do a second treatment a few days later though. And definitely do a big water change after treatment. You can try siphoning them out then. I'd probably run some carbon too.
