My battle with dinoflagellates

[Dash]

I love my tuxedo urchin. Spike is a nice small fellow & doesn’t cause too much trouble (I tried a beautiful white urchin that grew enormous in a couple of months & he disrupted things so much that I took him back to JL). Sometimes I move him onto a rock that needs cleaning and he’ll do it haha. He’s also been with me since the beginning so around 3 years old now at least. I don’t have big long clumps of HA though, just small patches here & there. He scrapes rock clean, leaving a white trail

I have a tuxedo urchin you could have for a reasonable amount. Not much algae left in my tank and he loves putting things on his back, snails, small corals ect. Kind of want to get rid of him.

I'm impressed with your ability to keep things alive for so long. I would hope it would eat the hair algae. I have a yellow tang that ignores it so I don't want more things that won't touch it.

I will probably take you up on that. I need to get my nitrates down a bit first. They are at 15-20ppm and from a quick google about them it seems they can be sensitive to nitrates.
