red cyano

Does anyone know what CUC can eat this stuff, I dont want to dose with anything just wanna find some type of CUC creature to attack this.

Thanks
Joe

 

Nassarius snails

 

they say a lot of things eat the stuff but not Nassarius snails they are carnivores .red legged hermits, pods, and sally lightfoot crab imo did the best but imo ur better off finding the source and fixing the problem they're a lot of threads on this subject

 

FFlow will do more than a CUC in controlling cyano. Also, lack of nutrients. The great thing about this stuff too, is that is just peels off. I have had a cyano problem for the last six months. It comes and goes (when I do the peel).

 

Its only on all my live rock in the tank, it started mainly after i used my homemade fish food and I told my wife to start feeding them at night so 2x a day but i think so overfed for about a week. Ive cut down to once a day feeding in really small portions and it looks like its stopped growing for right now. Just wanted to add some crabs or somethign to kill whats left in the tank.

 

I just went through 3 weeks of cyano.... bought 20 blue leg hermits on the advice they'd eat it... no they don't.

bought more ceriths on the advice they'll eat it... they don't.

Nassarius? Never even heard them suggested... they don't eat it in my tank tho.

bought a fighting conch... it eats it, any anything else near it's snout... but only off the sand, never off the rocks.

Oddly my female clown eats it sometimes. Makes her poop bright orange/red.

What finally seems to have it under control is limit phosphates.

Chemical export: Phosphate filter floss stuff (in the white bag)
Limit nutrients into the tank: I stopped feeding my fish 2-3 times a day.
Export what's been used already: sucked out all the large patches of cyano off the rocks and sand with 2x 20% water changes.

It's only been a few days since I feel I really got on top of it, but what was left behind is now mostly gone and i don't see any new growth.

CuC's for cyano are anecdotal at best, nothing I could find in scientific literature lists cyanobacteria in the diets of invertebrates or many reef fish. Of course, clowns aren't known to eat it and yet one of mine does. So you millage may vary on crabs and snails, but I don't think I'd bet much on them.

good luck with it, my outbreak wasn't the nightmare I've heard they can be, but I figured it would be better to get on it sooner than wait to see if it would resolve itself.

ceriths, nerites, blue legs, and chitons eat it, but it grows back so quickly if you have a large eastablished outbreak, nutrient export is the only way to effectively get it down, phosphate levels are high. cucs are better for dealing with normal cyano growth in a system that is just balancing out a little.

 

ya it looks like it stopped growing and has reduced in some spot, ive reduced feeding to once a day instead of 2x a day until i get more fish but I will see as it progresses over the next week or so and go from there. Im aquiring a kole tang soon so maybe ima be a lucky one and they will dine on a lil bit of it but who knows. Knock on wood its not as bad as some peoples but hopefully it wont get worse

 

In your case, I would consider, at least for now, cleaning it off the LR. I would perform a 30% water change and save the water. Mix up some more if needed (let sit overnight). Then split it out into three five gallon buckets. Two will be cleaning buckets and one rinse. Then just take a toothbrush to it. I did this the other day to most of my LR to remove that and hair algae. Then I cut my light to a few hours a day and reduced my feeding to twice weekly (four times weekly on algae strips). So far so good. But that will at least give you a good restarting point. And it won't significantly affect the bacterial population on the LR. The water in the tank will look oogy for a few hours while the dust settles, but in the end, it will look great.

 

Hermits generally will eat them when they are in a die off phase. At least that's what happens in my tank with blue legs. I cut the lights for 2-3 days and the cyano starts to die off, then the blue legs go and chow down.
