What Eats Red Slime Algae?

We have some hermit crabs and a sea urchin that eats all the green moss which I think is green hair algae, however red slime algae dominates our tank. To the point that it engulfs corals (I don't currently have any) my tank is right in front of a window (moving it isn't an option) so I have to clean weekly to be able to see through the glass. I also use a dowl rod to stir up the moss on the gravel.

I also forgot to mention we have snails as well!

HI there,
I believe dwarf zebra hermit crabs will eat RSA. You can also try lowering down your intensity, feed less and lowering down your lighting. Increasing the flow would also help.
Here is a thread about this topic:

Ive never tried to change my lighting intensity, but is it still worth the effort to change it my lights are LED?

Lowering the lighting could work. But you could always do the old Clean up crew and feed less way

 

dwarf zebra and cortez hermit crabs

Both are excellent Clean up crew members in my opinion

 

I don't keep saltwater but my Brother-in-law has had a lot of success with both for RSA

I've had experience with salt water before But I didn't like it as much.

I can't imagine I'm overfeeding that much, I never find any left overs, I feed them a cube of frozen shrimp every 1-2 days and a fourth of the cube goes in my quarantine which is currently holding my evil fish I need to take back to the store. Also when I don't feed shrimp cubes, I give them these little hikarI fish kibbles, again being very careful not to over feed.

I'm not saying that you are overfeeding I'm saying it MIGHT be caused by excess food. You can try introducing Clean up crew and see how it goes

Ohh, I thought you meant I was overfeeding, my mistake. Ill try though

It's all good. Good Luck and Tell is how it goes!

 

IME, red slime cyanobacteria is only cleared out by fixing whatever water parameter/light problems there are. I have not found a critter to rid my tank of it... ever.

You don't mention your water parameters. What are your nitrates and phosphates? What is your PH and salinity?

Do you rinse the food before you feed it or are you putting the piece of frozen food directly into the aquarium?

Sorry, did you say your tank has gravel in it? If that is the case, this is not a good substrate for marine aquariums, and you really should consider removing the gravel and either replacing with sand or leaving the bottom bare. Even though you are stirring the gravel, food/waste gets trapped in the large gaps between pieces causing nitrate problems.
