Limpets and Coralline Algae

[pandaparties]

So I have a tank that's about 2 and I don't have any coralline algae, despite seeing good growth and healthy coral. At first I thought it was because I had a bunch of urchins but they were rehomed due to a lack of food and in the year they've been gone I still have none. I noticed patches that pop up from time to time (mostly on powerheads) but then it disappears shortly after. I never see any on rocks. I have a 500g tank with tens of thousands of limpets. Now I don't mind their presence (I think they look cool actually) and they do a bangup job on my algae but I'm beginning to think they are eating all my Coralline. Does anyone know if this is in their diet??

Some do eat coralline. They prefer the green algae, but if there is a short supply, they'll eat coralline too. Here's an article on them.

Well looks like I'll never have coralline algae lol, they are absolutely everywhere and I think I have the type that eat it. Oh well!

Years ago, I had some of the big ones from Hawaii and they were superb cleaners and never ate coralline that I noticed. Mostly they stayed on the glass and reproduced prolifically. Fast forward to this tank and I have introduced some of the tiny ones that reefcleaners sells but never saw them again after introduction. Never seen the big ones available again either.

Mine were 100% eating my coralline. I was having it only in spots that they never went, on the rocks it would show up and be gone the next day. After introducing a fish that snacked on them i started having it grow all over my rocks. I used to have tens of thousands of them!

Melanurus will eat Limpets. Triggers and some puffers as well.
