Algae on anubias
My anubias's leaves are always covered in some type of algae and recently they have also started to get a small hair-like growth on them which is black and makes them look really ugly.
Just wondering if anyone can tell me what the algae is and what the hair-like stuff is and also how to get rid of them if possible as they dont just rub off the leaves. I've also got 2 BN plecos which dont seem to be eating it.
Heres a photo of one of the leaves. Its hard to see but there are dark green spots all over it aswel as small black dots.
The closest leaf to the camera in this photo has the hair-like stuff on the very tip although it is also hard to see.

Looks like Green Spot and Green Hair like Algae. Have that myself. I have a wide array of eaters, but the main thing I'm doing to combat it is water movement and keeping the lights at a minimum. Algae is better adapt to using the nutrients in the water column than plants, so takes some doing to knock it's population down.
Turn down the lights to about 8-10 hours, increase water movement if possible near the plants, and trim off the really affected leaves. On the eater front, BN most likely won't touch, neither will Otto Cats, and some others. I think maybe Nerite Snails will and some Shrimp.
A combo attack should help. Also, if it's on the glass, scrap it off/out of tank.

Thanks for the reply.
I scrape it off the front of the glass although I cant get to the back, I may need to buy an algae scrubber with a handle instead of the current magnetic one I have.
Also I have read somewhere that plants dont like heaps of water movement? Is this true?
Since I have YoYo Loaches Im not sure snails would survive but I'll give them a go. How would a true Siamese Algae Eater go with the hair algae?
Thanks for the reply, very helpful.

A true one might take a few whacks at it. You don't need a whole scrapper to get the job done, I cheap out and just buy the refill blades.
On the movement, plants would be ok with it, long as it's not full river style movement. A nice slow current won't hurt the plants and you'll probably notice algae will only be an issue in dead movement spots.
The Loaches might make a meal out of the Nerites, despite them being tightly squeezed in their shell. Will be a gamble if you do then.

A true Siamese Algae Eater will eat hair algae - any of the false ones will not touch the stuff. Just remember, they prefer other algae and will eat that first until the hair algae is mostly left - they won't target it. These algae eaters can get aggressive when older. Most plants are indifferent to water movement.

Another thing to remember, is the reason algae has bloomed, is because of an imbalance in your tank. This imbalance can be a number of things, such as lighting, nutrients (ferts), Chemistry, etc. It won't really cease until that balance is restored. So, lowing light time as I mentioned would help in the long run. Also, there's no real full time eater, just some that will help.
Flow helps, light time helps, and eaters help.
Another option is chemical. I wouldn't do this personally, but its an option.

Thank you very much for the replies! The light is currently on for 10 hours a day, I will lower it to 8 hours and see how that goes.

It looks like the beginning of BBA, on everything, not just on the Anubias. Green Spot algae on the glass.
The picture isnt really clear, I cant tell if there is a nutrient deficiency with yellow leaves & green veins, or if the color balance of the picture is off.

No the leaves are not yellow must be the crappy photo.
But could the plants have a nutrient defficiency, because the leaves on my 3 Wisteria are slowly dying (it looks as they are drying out or something)? I dose once a week with Flourish as per instructions on the bottle.
